Popes and Antipopes

Question: Honorius II: Answer: Honorius II's pontificate achieved reform within the church and peace between the Holy See and world rulers. He supported the election of Count Lothar II/III of Supplinburg as the German king (1125).

Question: Theodore I: Answer: Of Greek descent, Theodore I was noted for his generosity to the poor, though he had to devote most of his pontificate to combatting monothelitism, a heresy maintaining that Christ had only one will, which continued to find favor in the East.

Question: Agapetus II: Answer: The chief events of the pontificate of Agapetus II included the spread of Christianity in Denmark, the settlement of the dispute over the see of Reims, and the German king Otto I’s first success in Italy (951). Toward the end of his pontificate, Alberic II, then ruler of Rome, had the dying pope swear his support for Octavian, Alberic’s son, as next pope.

Question: Nicholas IV: Answer: Nicholas IV relied heavily on a powerful Italian family, the Colonna, and increased the number of Colonna cardinals. In a bull of 1289 he granted half of the church’s revenues and a share in its administration to the College of Cardinals, thereby increasing their importance in church and Papal States affairs.

Question: Boniface II: Answer: Boniface II was the first Germanic pontiff. He convoked three Roman synods: in that of 530 he received the submission of his opponents; in the first of 531 he proposed the right of a pope to select his successor; in the second of 531 he annulled the succession arrangement.

Question: Theodoric: Answer: As cardinal bishop of Santa Ruffina, Theodoric was elected pope by the faction headed by the Holy Roman emperor Henry IV during the struggle between empire and papacy. In 1101, however, Theodoric was seized by the supporters of the legitimate pope, Paschal II, who had him confined to the Holy Trinity monastery, near Salerno, where he died.

Question: Innocent X: Answer: In Rome, Innocent X attacked Pope Urban VIII's relatives, the Barberini, for extortion and confiscated their property. Innocent X clashed with France when the Barberini took refuge in Paris with Cardinal Mazarin, whose threat to invade Italy forced Innocent to yield. In theological matters he intervened in the quarrel between the Jesuits and the Jansenists and in a bull of 1653 condemned five propositions concerning the nature of grace as interpreted by Bishop Cornelius Jansen, the founder of Jansenism.

Question: Boniface IX: Answer: Boniface IX, viewing schism as a political problem, resorted to all possible means of raising money in order to win allies against the Avignon antipopes Clement VII (whom he excommunicated) and Clement’s successor, Benedict XIII. Boniface not only failed to end the breach, but he also aroused hostility by his high-handed methods to raise the large sums of money required for his campaigns.

Question: Gregory XIII: Answer: Gregory XIII promulgated the Gregorian calendar and founded a system of seminaries for Roman Catholic priests.

Question: Albert (also called Aleric): Answer: Albert was cardinal bishop of Silva Candida when elected early in 1101 as successor to the antipope Theodoric of Santa Ruffina, who had been set up against the legitimate pope, Paschal II, by an imperial faction supporting the Holy Roman emperor Henry IV in his struggle with Paschal for supremacy.

Question: Pius V: Answer: Pius V was an Italian ascetic, reformer, and relentless persecutor of heretics. His papacy marked one of the most austere periods in Roman Catholic church history. During his reign, the Inquisition was successful in eliminating Protestantism in Italy, and the decrees of the Council of Trent (1545–63) were put into effect.

Question: John XXII (at Avignon): Answer: John XXII was the second Avignon pope. He centralized church administration, condemned the Spiritual Franciscans, expanded papal control over the appointment of bishops, and, against the Holy Roman emperor Louis IV, upheld papal authority over imperial elections.

Question: Victor II: Answer: After his consecration on April 13, 1055, Victor II joined the Holy Roman emperor Henry III at Florence. There, in June, they held a council that condemned clerical marriages and simony.

Question: Boniface VII (2nd time): Answer: A cardinal deacon, Boniface VII ordered the murder of his predecessor, Benedict VI, and was installed by Crescentius I. Later, however, he was expelled at the behest of Otto II, the Holy Roman emperor, and was replaced on the papal throne by Benedict VII.

Question: Clement (III): Answer: When Guibert—Clement (III)—became the Italian leader of the imperialist faction opposing the Gregorian Reform, Gregory excommunicated him. Clement (III) was elected antipope on June 25, 1080, by a synod convoked by Henry at Brixen, which declared Gregory deposed.

Question: John VII: Answer: Elected March 1, 705, John VII was noted for his devotion to the Virgin Mary and for his energetic restoration of Roman churches. John did not recognize the decrees of the Council of Trullo (Constantinople, 692), submitted by the Byzantine emperor Justinian II, which included disapproval of such customs as celibacy of the clergy and rules for fasting.

Question: John XIII: Answer: John XIII was bishop of Narni, Papal States, when chosen pope on October 1, 965, by Emperor Otto I, and as pope he strongly supported Otto’s ecclesiastical and political policies. Although John was a pious and learned man, the Roman nobles opposed Otto’s choice and kidnapped John (December 965).

Question: John III: Answer: Records of John III’s pontificate were destroyed during an invasion of Italy by the Lombards, whose kingdom was in northern Italy.

Question: Vitalian: Answer: Consecrated as St. Eugenius I’s successor on July 30, 657, Vitalian soon dealt peacefully with monothelitism. In 668 Vitalian consecrated St. Theodore of Tarsus as the first archbishop of Canterbury to rule the whole English church.

Question: Gregory III: Answer: Gregory III was immediately confronted with the Iconoclastic Controversy, begun when his predecessor St. Gregory II condemned the Byzantine emperor Leo III’s destruction of religious images. Gregory denounced the Iconoclasts at a Roman council in 731.

Question: Pius XI: Answer: In 1938, eight months before Pius XI's death and 15 months before the outbreak of World War II, Pius secretly commissioned a fourth encyclical that would have denounced racism and the persecution of the Jews and explicitly condemned anti-Semitism. Pius XI died before his encyclical could be issued, and the draft was shelved by his successor, Pius XII, who decided to pursue a less confrontational course toward the fascist regimes.

Question: Paschal I: Answer: In 823 Paschal I crowned Louis I’s son Lothar I as co-emperor of the Franks, a deed that was significant because it initiated the handing of a sword by the pope to the emperor as a symbol of the temporal power that was to suppress evil. It also formalized the practice of crowning the emperor in Rome.

Question: Julius I: Answer: Julius became the chief supporter of orthodoxy and the Nicene Creed against Arianism, a heresy that held Christ to have been human, not divine.

Question: John IX: Answer: John IX's councils condemned Pope Stephen VI’s synod and destroyed its acts, restored the clergy deposed by Stephen and his faction, and confirmed the Constitutio Romana of the Frankish emperor Lothar I, thereby making compulsory the presence of an imperial emissary at papal consecrations.

Question: Paschal: Answer: Paschal was an antipope against both the rival antipope Theodore and the legitimate pope Sergius I during 687. After the death of Pope Conon in September 687, the Roman populace proceeded to enthrone both Paschal, then an archdeacon, and the archpriest Theodore.

Question: Leo IV: Answer: Leo IV rebuilt Rome after it had been sacked by Arab enemies in 846 and fortified the city to protect it against future attacks. At a Roman synod in April 850, he crowned as co-emperor the Frankish emperor Lothar I’s son Louis II. In church affairs, Leo took a firm hand against abuses by important ecclesiastics.

Question: Nicholas V: Answer: Nicholas V was an influential Renaissance pope and founder of the Vatican Library. Soon after his election, he brought to an end the schism caused by rivalries between popes and councils.

Question: Celestine I: Answer: Celestine's pontificate is noted for its vigorous attack on Nestorianism, the unorthodox teaching of Patriarch Nestorius of Constantinople, which stressed that Christ’s human and divine natures were independent and which denounced the Virgin’s title Theotokos (God-bearer).

Question: Benedict III: Answer: Benedict III reprimanded the Frankish bishops, whose inaction he blamed as the source of misery in their empire, and reasserted Rome’s primatial authority over Constantinople. Benedict also was responsible for the repair of Roman churches damaged by enemies in 846.

Question: Pius II: Answer: Pius II was an outstanding Italian humanist and astute politician who as pope tried to unite Europe in a Crusade against the Ottoman Turks at a time when they threatened to overrun all of Europe. He wrote voluminously about the events of his day.

Question: Adeodatus II: Answer: Adeodatus II devoted his attention to restoring churches in a state of disrepair. A Benedictine monk, he took the Abbey of St. Peter and St. Paul (St. Augustine’s) under his protection; he improved the Monastery of St. Erasmus; and he seems to have recognized the exemption of the Abbey of St. Martin of Tours from episcopal authority.

Question: Stephen IX (or X): Answer: Stephen IX (or X) was one of the key pontiffs to begin the Gregorian Reform. He convoked a Roman synod to denounce simony (i.e., the buying or selling of a church office), zealously enforced clerical celibacy, and centralized the reform. Among the celebrated reforming ecclesiastics employed by Stephen were Cardinal Peter Damian, the powerful Roman cardinal Humbert of Silva Candida, and Cardinal Hildebrand (later Pope Gregory VII).

Question: Calixtus III (Callistus): Answer: The repulse of the Ottoman Turks from Belgrade on August 6, 1456, was commemorated by Calixtus III when he instituted the Feast of the Transfiguration (1457), ordering that it be observed on that day. Calixtus III's pontificate also revised St. Joan of Arc’s trial by proclaiming her innocence.

Question: John IV: Answer: John IV was against the date for Easter favored by Celts in Ireland, and he defended the highly controversial orthodoxy of Pope Honorius I, who had held that Christ’s human and divine natures were indivisible and that the Son’s will was not different from that of the Father.

Question: Sixtus III: Answer: Sixtus III sponsored important building projects in Rome in the aftermath of the sacking of the city by the Visigoths in 410, including a reconstruction of the Liberian Basilica (now St. Mary Major) and the erection of a second basilica adjoining the 4th-century church of St. Lawrence Outside the Walls.

Question: Gelasius I: Answer: Gelasius’s doctrine that both sacred and civil power are of divine origin and independent, each in its own sphere, was then the most progressive thinking on the subject; had his formula been established, the subsequent history of the papacy probably would have been different.

Question: Celestine V: Answer: Celestine V was the first pope to abdicate. On the verge of escaping via the Adriatic Sea, Celestine V was captured and sent back to Pope Boniface VIII, who kept him interned in Fumone Castle, where he died. Dante places him at the entrance of Hell for his abdication and alludes to the pope (Inferno III, 59ff.) as “…him who made, through cowardice, the great refusal.”

Question: Paul I: Answer: Paul I's alliance with the Franks strengthened the young Papal States. He secured the support of the Frankish king Pippin III the Short against the animosity of the Lombard king Desiderius and the Byzantine emperor Constantine V Copronymus.

Question: Pelagius I: Answer: Pelagius was unable to prevent the bishops of Milan and Istria from schism because as pope he reversed his opposition to the Fifth Council and upheld the Council of Constantinople.

Question: Clement V (at Avignon): Answer: For yielding to France and complying with Philip, for turning against Henry, for practicing simony (selling ecclesiastical offices), and for transferring the papal see from Rome to Avignon, Clement V was censured by Dante in Inferno XIX as “a shepherd without law, of uglier deed” and a “new Jason.” He was responsible for the “Babylonian Captivity” (1309–77), during which the papacy abandoned its traditional residence in Rome for Avignon.

Question: Nicholas (V) (at Rome): Answer: After Pope John XXII (at Avignon) excommunicated him in April 1329, Nicholas (V), having been assured a pardon, renounced at Avignon his illegal claim to the papacy on August 25, 1330. Nicholas remained in honorable imprisonment in the papal palace until his death.

Question: Urban V (at Avignon): Answer: Urban V helped to restore peace in Italy and began to reform the Avignonese Curia, which in 1365 he planned to reestablish at Rome, despite French opposition. Urban also felt the reunion of the Eastern and Western churches was urgently important and that negotiations with the patriarch of Constantinople would be facilitated if the papacy were back in Rome.

Question: Julius III: Answer: Julius III's interest in the Society of Jesus (the Jesuits, a religious order founded by Ignatius of Loyola) influenced him to establish the Collegium Germanicum (1552) to train German priests in Rome under that order. His patronage of Renaissance thought led him to reform the Roman University, to build the Church of St. Andrew in Rome, and to appoint Palestrina choirmaster of St. Peter’s, with Michelangelo as the church’s principal architect.

Question: Innocent II: Answer: Innocent II confirmed the rule and customs of the Templars, one of the three orders of knighthood founded during the Crusades. At the Council of Sens (1140), Innocent II supported the prosecution of the theologian-philosopher Abbot Peter Abélard and his supporter, Arnold of Brescia, by condemning them as heretics.

Question: Gaius: Answer: Gaius was supposedly a relative of the Roman emperor Diocletian. He conducted his pontificate at a period of Diocletian’s reign when Christians were tacitly tolerated.

Question: Gregory IV: Answer: Gregory IV promulgated the observance of the Feast of All Saints (November 1) and conferred the pallium—i.e., granted the symbol of metropolitan jurisdiction—on the Frankish missionary St. Ansgar, the apostle of Scandinavia.

Question: Urban IV: Answer: Urban IV was faced with three tasks: freeing the Kingdom of Sicily, a papal fief, from domination by the Hohenstaufen dynasty of the Holy Roman Empire; reasserting papal influence in Italy, where it had diminished because of Alexander’s vacillation on the Sicilian problem; and restoring order in Rome, which suffered such civil unrest that Urban never resided there as pope.

Question: Alexander IV: Answer: Alexander IV supported the new mendicant orders, especially the Franciscans, upholding the friars at Paris against the secular professors. He extended the Inquisition in France, worked for reunion between eastern Christians and Rome, and attempted in vain to organize a Crusade.

Question: Gregory (VIII): Answer: On Pope Paschal II’s death, the Holy Roman emperor Henry V set Gregory (VIII) up as antipope against Pope Gelasius II, but Gregory was excommunicated by Gelasius (1118) and by Pope Calixtus II (1119). Imprisoned in a series of monasteries, he died in exile in 1140.

Question: Benedict XV: Answer: By 1919 the papacy lacked the prestige it had enjoyed under Pope Leo XIII, and Benedict XV was excluded from peace negotiations following World War I. Benedict's last years were concerned with readjusting the machinery of papal administration made necessary by the territorial changes that followed the war and with directives on missionary work.

Question: Stephen IV (or V): Answer: In Reims Stephen (IV or V) anointed the Carolingian emperor Louis I as Holy Roman emperor, an act that solidified the alliance between the papacy and the Franks and created effects crucial to European history. The papacy became the agency that created emperors, symbolized by the coronation and anointing, and this became one of the papacy’s most treasured prerogatives.

Question: Calixtus I (Callistus): Answer: After the death of Pope Zephyrinus (217), Calixtus was elected pope but was opposed by his theological adversary Hippolytus, who attempted to supplant him and who accused him of favoring modalist, or Patripassian, doctrines, both before and after his election. (Calixtus, however, condemned and excommunicated Sabellius [flourished c. 215–c. 220], the most prominent champion of modalistic monarchianism, called Sabellianism, a heretical doctrine that denied personal distinctions within the Godhead.)

Question: Clement (VII) (at Avignon): Answer: Clement VII was a leader of the cardinals who declared the unpopular Italian pope Urban VI’s election invalid, and he was chosen antipope at Fondi, Papal States, as Clement VII on September 20, 1378. Clement VII's coronation in October precipitated the Great Schism of the West (1378–1417).

Question: Benedict XII (at Avignon): Answer: Benedict XII issued a bull, Benedictus Deus (1336), in which he formulated the church’s teaching that the souls of the just are granted the Beatific Vision immediately after death. In Avignon he built a costly papal palace and brought in Sienese artists to decorate the local churches.

Question: John I: Answer: John I ended the Acacian Schism (484–519), thus reuniting the Eastern and Western churches by restoring peace between the papacy and the Byzantine emperor Justin I. He also ratified the Alexandrian computation of the date of Easter, which was eventually accepted throughout the West.

Question: Adrian II: Answer: Adrian II approved the use of the Slavic language in liturgy by Saints Cyril and Methodius. By making Methodius archbishop of Sirmium, Adrian won the Moravians’ faithfulness.

Question: Paschal (III): Answer: By imperial command in 1165 Paschal (III) canonized Charlemagne at Aachen, a decree never confirmed by the church, although Charlemagne is now regarded as having been informally beatified.

Question: John XIV: Answer: The antipope Boniface VII had been expelled by the Holy Roman emperor Otto II but returned to Rome when Otto died (December 7, 983). Aided by the powerful Roman family the Crescentii, Otto imprisoned John XIV in the Castel Sant’Angelo, Rome, and presumably had him murdered, either by starvation or by poison.

Question: Clement IV: Answer: Clement IV executed the plan of Pope Urban IV, his predecessor, in a century-old battle between the papacy and the German Hohenstaufen family. For military and financial help against King Manfred of Sicily, a Hohenstaufen, Clement IV made Charles of Anjou king of Naples and Sicily in 1266.

Question: John Paul II: Answer: John Paul II was the first non-Italian pope in 455 years and the first from a Slavic country. As part of his effort to promote greater understanding between nations and between religions, he undertook numerous trips abroad, traveling far greater distances than had all other popes combined.

Question: Innocent XII: Answer: In 1693 Innocent XII broke the politico-religious deadlock between King Louis XIV of France and the Holy See by influencing Louis to disavow the four Gallican Articles of 1682 issued against Innocent XI. In exchange, Innocent XII agreed to extend the king’s right to administer vacant sees.

Question: Boniface VII (1st time): Answer: Boniface VII, original name Franco, was pope, or antipope, from June to July 974 and from August 984 to July 985; he owed his rule to the support of the Crescentii, a powerful and unscrupulous Roman family.

Question: Christopher: Answer: Christopher appears in many lists of the popes (including the Liber Pontificalis, edited by Louis Duchesne, and Pontificum Romanorum), but he is now regarded as an antipope.

Question: Donus: Answer: Donus ended a schism created by Archbishop Maurus of Ravenna (whose plan was to make Ravenna ecclesiastically independent) by receiving the obedience of Maurus’s successor Reparatus.

Question: Adrian III: Answer: Adrian III died en route to the Diet of Worms after being summoned by the Frankish king Charles III the Fat to settle the succession to the empire. His death under dubious circumstances led many to believe that he had been assassinated.

Question: Celestine II: Answer: As pope, Celestine II immediately removed Innocent’s interdict against King Louis VII of France. Celestine died on the verge of a controversy with King Roger II of Sicily regarding Roger’s prerogatives as apostolic legate.

Question: Marcellus I: Answer: Marcellus I succeeded Marcellinus after an interval of three or four years. The penances that he imposed on apostates resulting from the persecutions of Christians by the Roman emperor Diocletian led to rioting.

Question: Clement III: Answer: In October 1187 Jerusalem fell to Saladin, the leader of the Muslim armies, and Clement III called the Western princes to undertake the Third Crusade.

Question: John: Answer: John, an antipope, was saved from being murdered by the noble faction through the intervention of Pope Sergius II, who then imprisoned him in a monastery. The following June, Sergius was finally approved by the Frankish emperor Lothar I, and John’s subsequent history is unknown.

Question: Leo IX: Answer: The most significant event of Leo IX’s pontificate—the actual break with the Eastern church—resulted, at least partially, from an ill-fated military involvement.

Question: Anastasius IV: Answer: Crowned in the Lateran Palace in Rome, Anastasius IV spent lavishly for its restoration and that of the Pantheon. During his brief pontificate he was a peacemaker noted especially for settling two long-standing problems: one regarding the Holy Roman emperor Frederick I Barbarossa and the see of Magdeburg, the other regarding St. William of York and his see.

Question: Laurentius: Answer: Laurentius was the antipope whose disputed papal election gave his name to the Laurentian schism.

Question: Eutychian: Answer: Eutychian was the last pope to be buried in the catacombs, but nothing more is known of him.

Question: Lucius II: Answer: When King Roger II of Sicily invaded papal lands and forced Lucius II to accept his truce, Anacletus’s brother, the patrician Giordano Pierleoni, led the Romans to proclaim a constitutional republic free from papal civil rule. Lucius II opposed this bid for Roman independence, led an unsuccessful assault against the rebels, and presumably died from injuries suffered in the conflict.

Question: Pius IX: Answer: Pius IX's pontificate was marked by a transition from moderate political liberalism to conservatism. Notable events of his reign included the declaration of the dogma of the Immaculate Conception (1854), the Syllabus of Errors (1864), and the sessions of the First Vatican Council (1869–70), during which the doctrine of papal infallibility was authoritatively defined.

Question: Sylvester I: Answer: According to subsequent legend, Sylvester converted and baptized Constantine, who was the first Roman emperor to become a Christian, and miraculously cured him of leprosy. In return the emperor allegedly gave him the Donatio Constantini (Donation of Constantine), a grant of spiritual supremacy over the Eastern patriarchates and over all matters of faith and worship as well as temporal dominion over Rome and the entire Western world.

Question: John II: Answer: John II opposed Nestorianism, the heresy that separated the divine and human natures of Christ and denied the Virgin Mary the title Mother of God.

Question: Clement VI (at Avignon): Answer: Clement VI's pontificate was confronted by three problems: the last of the Crusades, the failure of the Florentine bankers, and the state of papal possessions in Italy. He helped secure the election in 1346 of the German king Charles IV, who allied with the papacy.

Question: Celestine IV: Answer: Celestine IV was the first pope to be elected in a conclave, which had been set up by the senator of Rome, Matthew Rosso Orsini, who hoped to break a deadlock of 60 days in the College of Cardinals. Celestine IV, an old and sick man, was consecrated on October 28 but died two weeks later during a controversy between the papacy and the Holy Roman emperor Frederick II.

Question: Leo X: Answer: Leo X was one of the leading Renaissance popes. He made Rome a cultural center and a political power, but he depleted the papal treasury, and, by failing to take the developing Reformation seriously, he contributed to the dissolution of the Western church. Leo excommunicated Martin Luther in 1521.

Question: Pius I: Answer: Pius I was a slave, according to his supposed brother, the apostolic father Hermas. As pope, Pius combatted gnosticism—a religious movement teaching that matter is evil and that emancipation comes through spiritual truth attained only by revelatory esoteric knowledge—and the Marcionites, followers of a heretical Christianity proposing especially a doctrine of two gods as taught by the semi-gnostic Marcion, whom Pius is believed to have excommunicated in 144/150.

Question: Urban VII: Answer: Prior to being elected pope, Urban VII held several key church offices, including papal ambassador to Spain (until 1572), cardinal priest (1583), and inquisitor general (1586). Known for his charity and piety, he was elected on September 15, 1590, but died of malaria 12 days later, before his consecration.

Question: Dionysius: Answer: In response to charges of tritheism—i.e., separating the members of the Trinity as three distinct deities—against Bishop Dionysius of Alexandria, Pope Dionysius convened a Roman synod (260) and demanded an explanation from Bishop Dionysius; this became known as “the affair of the two Dionysii.”

Question: Clement I: Answer: According to the early Christian writer Tertullian, Clement I was consecrated by St. Peter.

Question: Innocent XI: Answer: Innocent XI inherited an insolvent papal treasury but averted bankruptcy through taxation, rigid economizing, and financial support from Catholic powers. He aided the war against the Ottoman Turks by subsidizing King John III of Poland and the Holy Roman emperor Leopold I in a campaign that led to the relief of Vienna (1683) from siege.

Question: Severinus: Answer: Consecrated on May 28, 640, Severinus promptly declared the orthodoxy of Christ’s two natures and two wills. The condemnation of monothelitism, carried on by his immediate successors as well, caused strained relations between Rome and Constantinople for several decades.

Question: Gregory XII: Answer: Gregory XII was the last of the Roman line during the Western Schism.

Question: Anastasius III: Answer: Because Anastasius III's pontificate came during a period when Rome was under the control of the house of Theophylactus, he had little authority or freedom of action. He is credited, however, with granting privileges to ecclesiastical dioceses in Italy.

Question: Agatho: Answer: Agatho prevailed upon the Byzantine emperor Constantine IV to abolish the tax formerly exacted at the consecration of a newly elected pope, which helped establish good relations between Rome and Constantinople. Agatho died during a plague that ravaged Rome.

Question: Gregory XI (at Avignon, then Rome): Answer: On January 17, 1377, Gregory XI returned the papacy to Rome over the opposition of France and of several cardinals. Although his months there were marked by strife and led him to flee temporarily to Anagni, his move back to Rome was a highly significant act in papal history, for the papacy, despite the reign of later antipopes in other cities, thenceforth remained at Rome.

Question: Boniface I: Answer: Boniface’s reentry into Rome ended a 15-week schism. Thereafter his pontificate was noted for his peaceful, yet firm, diplomacy and for his zealous support of Bishop St. Augustine of Hippo, particularly in the fight against Pelagianism, a heresy that denied original sin.

Question: Leo VII: Answer: Leo VII encouraged reform of the German clergy and forbade Archbishop Frederick of Mainz to enforce the conversion of Jews to Christianity, yet at the same time allowed him to expel all Jews who would not embrace Christianity.

Question: Romanus: Answer: Under Romanus, the body of Pope Formosus was retrieved from the Tiber River and buried. Romanus probably invalidated the acts of his predecessor, Stephen, although formal nullification was not promulgated until a few years later by Pope John IX. Romanus was deposed, probably by Stephen’s faction.

Question: Felix IV (or III): Answer: Felix IV ended the controversy over grace at the second Council of Orange (529) by condemning Semi-Pelagianism, which maintained that the beginning of faith results from human effort rather than grace.

Question: Clement XIV: Answer: Portugal had already been in schism for nine years because the Jesuits, whom King Joseph I considered to be an impediment to his monarchical ambitions, had not been exterminated. Fearing that France and Spain would resort to open schism, Clement XIV finally yielded and on July 21, 1773, issued the brief Dominus ac Redemptor (“Lord and Saviour”) dissolving the Society of Jesus, which from its inception had dedicated itself to the service of the pope.

Question: Benedict V: Answer: Benedict V was also known as Benedict the Grammarian. He was pope, or antipope, from May 22, 964, to June 23, 964, when he was deposed. His election by the Romans on the death of Pope John XII infuriated the Holy Roman emperor Otto I, who had already deposed John and designated Leo VIII as successor.

Question: Anacletus (II): Answer: Two claimants to the papacy were consecrated on February 23, 1130, leading to a serious schism. Anacletus (II), backed by most Romans and by the Frangipani, forced Innocent II to flee from Rome to France, where he was supported by Abbot St. Bernard of Clairvaux, who attacked Anacletus’s Jewish ancestry. Although Anacletus (II) was allied with the ambitious and powerful Roger II after investing him as king of Sicily (1130), Innocent’s supporters, including the Holy Roman emperor Lothar II and the Byzantine emperor John II Comnenus, were overwhelming.

Question: John V: Answer: John V, a man of learning and generosity, he made liberal donations for the poor. Seriously ill during his brief pontificate, he accomplished little.

Question: Innocent IX: Answer: Innocent IX assumed practically all administration under the ailing pope Gregory XIV, whom he was chosen to succeed as pope as a short-term replacement acceptable to all. He then died two months after assuming the papacy.

Question: Constantine (II): Answer: Constantine II, failing to win support from the Carolingian king Pippin III the Short or from the Franks, was deposed in 768 by a Lombard army and imprisoned in a monastery, where he was attacked and blinded. His deposition was canonically ratified by a council of Italian and Frankish bishops.

Question: Sixtus IV: Answer: Sixtus IV established and richly endowed the first foundling hospital and repaired and built numerous Roman churches (including Santa Maria del Popolo and Santa Maria della Pace); the Sistine Chapel is his principal monument. He commissioned such great artists as Sandro Botticelli and Antonio del Pollaiuolo and pensioned such eminent men of learning as Bartolomeo Platina. From 1471 he was the second founder of the Vatican Library, which he opened for scholars.

Question: Nicholas II: Answer: At his first council, held in the Lateran Palace at Easter in 1059, Nicholas II issued a decree on papal elections, which was intended to prevent interference by the nobility and to regularize the succession. Nicholas II assigned a leading role to the seven cardinal bishops, who were to choose a suitable candidate and then summon the other cardinals.

Question: Damasus I: Answer: Rome’s primacy was officially pronounced by a synod called in Rome in 382 by Damasus, who was perhaps wary of the growing strength of Constantinople, which was already claiming to be the New Rome. St. Jerome attended the synod and stayed on to become Damasus’s secretary, close adviser, and friend. Damasus commissioned him to revise the Latin translations of the Bible for what subsequently became known as the Vulgate.

Question: Theodore: Answer: A Roman archpriest, Theodore had already been a papal candidate when Pope John V died. Following the death of John’s successor, Pope Conon, a simultaneous double election conducted by opposing factions attempted to enthrone Theodore and his rival, the antipope Paschal, then a Roman archdeacon.

Question: Celestine III: Answer: Celestine III weakly supported the Crusade organized by the Holy Roman emperor Henry VI, which would probably have led to a Latin conquest of the Byzantine Empire earlier than it occurred. In his 90s, Celestine III sought to abdicate at the end of 1197, but the cardinals refused his request.

Question: Gregory X: Answer: Gregory X saved the Holy Roman Empire from disintegrating by promoting the election of Rudolf I of Habsburg as emperor.

Question: Clement XII: Answer: Although Clement XII's protests against the spread of Gallicanism (an essentially French doctrine advocating restriction of papal power) to Spain were fruitless, his enforcement of Pope Clement XI’s bull Unigenitus of 1713 sustained the suppression of Jansenism (a heretical doctrine deemphasizing freedom of the will and teaching that redemption through Christ’s death is open to some but not all). In Rome he erected the Trevi Fountain.

Question: Fabian: Answer: Fabian was an outstanding administrator and one of the great popes of the early church. Fabian supposedly divided Rome into seven districts assigned to the seven deacons and is said to have founded several churches in France.

Question: Innocent III: Answer: When the barons of England forced King John to sign the Magna Carta, Innocent III declared the charter null and void because it violated his rights as feudal lord.

Question: Honorius IV: Answer: Although old and crippled, Honorius IV was elected on April 2, 1285, to succeed Pope Martin IV. His pontificate favored the mendicant orders (i.e., religious orders avowing poverty and mobility).

Question: Calixtus (III): Answer: Calixtus (III) was elected as Antipope Paschal III’s successor, in opposition to Pope Alexander III. Calixtus was the protégé of the Holy Roman emperor Frederick I Barbarossa until the Treaty of Anagni (1176), which ended the schism in Alexander’s favor with the proviso that Calixtus should have an abbacy to compensate for his deposition.

Question: Victor I: Answer: Under Victor I, Latin replaced Greek as the official language of the Roman church, and Victor himself wrote in Latin.

Question: Leo VIII: Answer: A Roman synod in December 963 deposed and expelled Pope John XII for dishonorable conduct and for instigating an armed conspiracy against the Holy Roman emperor Otto I the Great. Otto, who had marched into Rome with his army and had called the synod, subsequently influenced the election of Leo, then only a layman.

Question: Gregory IX: Answer: Gregory IX ordered the canonist Raymond of Peñafort to compile the Decretals, a code of canon law based both on conciliar decisions and on papal letters, which he promulgated in 1234. Gregory IX strengthened the Inquisition and entrusted its operations to the Dominicans.

Question: Leo XIII: Answer: Leo XIII renewed the condemnations of Rationalism—the theory that reason is the primary source of knowledge and of spiritual truth—and pursued with fresh vigor the reestablishment of the philosophy of St. Thomas Aquinas. In 1899 he condemned Americanism, a movement to reconcile Catholicism and American culture.

Question: Eusebius: Answer: Eusebius's epitaph, written by Pope Damasus I, tells of a violent dispute in Rome about readmitting apostates after the persecution of Christians under the Roman emperor Diocletian. Eusebius was opposed by a faction that wanted offenders readmitted to the church without penance.

Question: Innocent VI (at Avignon): Answer: In 1360 Innocent VI arranged the Treaty of Brétigny between England and France, which ended the first phase of the Hundred Years’ War. The last years of Innocent's pontificate were occupied with preparations for a Crusade and with negotiations for the reunion of the Roman and Eastern churches.

Question: Gregory XV: Answer: Gregory XV’s pontificate achieved two significant reforms: he introduced the secret ballot in papal elections, and he established the first permanent board of control of Roman Catholic foreign missions, the Congregation for the Propagation of the Faith, whose missionary work helped the church recover many of its losses from the Protestant Reformation. He canonized Saints Ignatius of Loyola, Francis Xavier, Philip Neri, and Teresa of Ávila.

Question: Martin IV: Answer: Martin IV excommunicated the Byzantine emperor Michael VIII Palaeologus for lack of sincerity in the cause of church unity shortly before Michael’s death (1282).

Question: Conon: Answer: Probably the son of a Thracian soldier, Conon was educated in Sicily and was ordained a priest in Rome.

Question: Pius IV: Answer: The Council of Trent was dissolved on December 4, 1563, and Pius IV confirmed its decrees and definitions in his bull Benedictus Deus (January 26, 1564); on the following November 3, he published a summary of doctrine generally known as the Professio fidei Tridentina (“Tridentine Profession of the Faith”), imposing it on the bishops as obligatory.

Question: Alexander II: Answer: His election as Pope Alexander II was opposed by the German court, which nominated Peter Cadalus of Parma as Honorius II. In 1062 Honorius was dropped by the German regents, and the schism ceased to be important.

Question: Alexander VI: Answer: As a patron of the arts, Alexander VI erected a center for the University of Rome, restored the Castel Sant’Angelo, built the monumental mansion of the Apostolic Chancery, embellished the Vatican palaces, and persuaded Michelangelo to draw plans for the rebuilding of St. Peter’s Basilica. Alexander VI proclaimed the year 1500 a Holy Year of Jubilee and authorized its celebration with great pomp. He also promoted the evangelization of the New World.

Question: Clement VIII: Answer: Clement VIII encouraged the Counter-Reformative efforts of St. Francis de Sales, whom he made bishop of Geneva in 1602, and was responsible for printing a corrected edition of the Vulgate (the standard version of the Latin Bible) and other key liturgical books. Clement VIII also expanded the Index of Forbidden Books and intensified the activity and scope of the Inquisition.

Question: Martin I: Answer: Martin I’s pontificate occurred during an extensive controversy that had strained relations between the Eastern and Western churches—namely monothelitism, a heresy maintaining that Christ had only one will. To bring an end to the controversy, Martin convoked and presided over the Lateran Council of 649 that condemned monothelitism and the Typos, an order by the Byzantine emperor Constans II Pogonatus that forbade discussion of Christ’s wills.

Question: Linus: Answer: Linus may have been the immediate successor to Peter. St. Irenaeus identifies him with the Linus in 2 Timothy 4:21 and writes that “the blessed Apostles passed on the sacred ministry of the episcopacy to Linus.”

Question: Sylvester III: Answer: Sylvester III was bishop of Sabina when elected pope in January 1045 by a faction that had driven Pope Benedict IX out of Rome. The following month, however, Benedict’s supporters in turn expelled Sylvester.

Question: Gregory VI: Answer: Gregory VI was elected pope on May 5, 1045, after he paid Pope Benedict IX to resign in order to save the papacy from scandal arising from Benedict’s licentious behavior. But Gregory VI was accused of simony at the Council of Sutri, Papal States, held by the Holy Roman emperor Henry III in 1046, and deposed on December 20, retiring to Germany with his chaplain Hildebrand, later Pope Gregory VII.

Question: Marcellinus: Answer: Marcellinus's pontificate saw a long tranquil period terminated by a renewed and bloody persecution of Christians, the last of its kind, by the Roman emperor Diocletian. It is believed that Marcellinus became an apostate during the persecution, offering incense to the pagan gods of Rome. Augustine of Hippo, however, discredits the charge.

Question: Pius VIII: Answer: In strictly ecclesiastical matters, Pius VIII was generally broad-minded and conciliatory; he delegated foreign policy to his secretary of state, Cardinal Giuseppe Albani. Although he opposed liberal movements in Ireland and Poland, Pius VIII accepted the July Revolution (1830) in France that deposed Charles X in favor of Louis-Philippe.

Question: Constantine: Answer: Constantine strongly objected to the canons, several of which opposed Roman customs, established by the largely eastern Trullan (or Quinisext) Council assembled under the Byzantine emperor Justinian II in 691. He was flatteringly received by Justinian, who summoned him to Constantinople in 710, probably to obtain his ratification of the Trullan Council.

Question: Dioscorus: Answer: Dioscorus was pope, or antipope, for 23 days. A deacon in the Alexandrian Church, he clashed with the miaphysites (Christians teaching that Christ has one nature, rather than two—i.e., human and divine).

Question: Leo V: Answer: Leo V was deposed and imprisoned by the antipope Christopher. Leo was perhaps murdered, either by Christopher or his successor, Pope Sergius III.

Question: Urban VIII: Answer: A promoter of the arts, Urban VIII was the foremost patron of the important Baroque sculptor and architect Gian Lorenzo Bernini, some of whose finest works he commissioned, including the loggias of St. Peter’s, Rome, and Urban’s tomb in the basilica. Reluctantly, Urban VIII had his friend Galileo tried and condemned for a short time in 1633.

Question: Benedict IV: Answer: Benedict IV excommunicated Baldwin II, count of Flanders, for causing the assassination of Fulk, archbishop of Reims; he crowned Louis III the Blind emperor in February 901.

Question: Marcellus II: Answer: With Cardinal Giovanni Maria Ciocchi del Monte (later Pope Julius III) and Cardinal Reginald Pole, Marcellus II presided at the Council of Trent in 1545. A leader in church reform, he died less than a month after being elected pope.

Question: Gregory VII: Answer: Gregory VII was one of the greatest popes of the medieval church. He was the first pope to depose a crowned ruler, Emperor Henry IV.

Question: Paul II: Answer: Paul II was a patron of scholars and also a collector of antiquities and a restorer of monuments. He was responsible for founding the first printing presses at Rome, where he had built the Palace of St. Mark (now the Palazzo Venezia), his principal residence from 1466.

Question: Innocent VIII: Answer: In a bull of 1484 Innocent VIII acknowledged belief in witchcraft, condemned it, and then dispatched inquisitors to Germany to try witches.

Question: Adrian VI: Answer: Adrian VI was elected pope on January 9, 1522, and was crowned at Rome on August 31. A Dutchman, he was the last of the non-Italian popes until the pontificate of John Paul II more than 400 years later. Adrian VI was resented by the Romans as an outsider.

Question: Sisinnius: Answer: Sisinnius was consecrated about January 15, 708. Threatened by the exarch of Ravenna, the Lombards, and the Muslims, Sisinnius ordered the walls of Rome reinforced.

Question: Sixtus II: Answer: Sixtus II was elected in August 257 to succeed Stephen I, during whose pontificate there arose a conflict with certain Eastern churches over the rebaptism of converted heretics. Although Stephen firmly upheld the Roman rule that rendered rebaptism unnecessary, Sixtus, supposedly influenced by Bishop St. Dionysius the Great of Alexandria, adopted a more conciliatory attitude by tolerating the Eastern policies of rebaptism.

Question: Boniface VIII: Answer: In 1296 Boniface VIII issued the bull Clericis laicos, which forbade under the sanction of automatic excommunication any imposition of taxes on the clergy without express license by the pope. This bull had some effect in England, chiefly because of its support by the archbishop of Canterbury, Robert Winchelsey, but in France there was no strong defender of papal prerogative against the concerted action of the king and his civil lawyers.

Question: Benedict VI: Answer: Benedict VI was imprisoned in June 974 in the Castel Sant’Angelo and replaced by the deacon Franco, later known as antipope Boniface VII, who purportedly, by order of Crescentius I de Theodora, strangled Benedict.

Question: John XII: Answer: John XII rebelled when the Holy Roman emperor Otto I issued his controversial Privilegium Ottonianum (“Ottonian Privilege”), which ordered John to take an oath of obedience to the emperor.

Question: John (XXIII) (at Bologna): Answer: After the Council of Constance (1414–18) threatened to investigate his life, the antipope John XXIII promised to resign if his two rivals also resigned, but instead he fled. Enraged, the council deposed him on May 29, 1415. It then received Pope Gregory XII's resignation, condemned the antipope Benedict XIII, and elected Pope Martin V, thus restoring church unity.

Question: Evaristus: Answer: Evaristus was pope during the reign of the Roman emperor Trajan.

Question: Innocent (III): Answer: A member of a family of German origin, Innocent (III) was a cardinal when elected on September 29, 1179, by a faction opposing Pope Alexander III, who, in January 1180, relegated Innocent to the southern Italian abbey of SS. Trinità in La Cava, where he died.

Question: Francis: Answer: In November 2013 Francis issued Evangelii Gaudium (“The Joy of the Gospel”), an apostolic exhortation in which he denounced economic inequality and called upon the church to embrace its global diversity. In August 2014 he publicly denounced the alleged persecutions of Christians and religious minorities such as the Yazīdīs by the transnational Sunni insurgent group the Islamic State in Iraq and the Levant.

Question: Nicholas I: Answer: Nicholas I was a master theorist of papal power. He is considered to have been the most forceful of the early medieval pontiffs. His pontificate was the most important of the Carolingian period and prepared the way for the 11th-century reform popes.

Question: Philip: Answer: Backed by some Romans, the Lombards, in 768, secretly set Philip up as pope. Philip was ejected, however, and Stephen III (IV) was elected pope on August 1, 768, at which time Philip retired to his monastery.

Question: Sergius II: Answer: Sergius II's pontificate was dominated by his brother, Bishop Benedict of Albano, to whom, partly because of his severe gout, he delegated most of the papal business. Benedict proved opportunistic, however, usurping power and finagling money while executing a large building program that included the enlargement of the St. John Lateran Basilica.

Question: Eugenius II: Answer: In 824 Eugenius received the Holy Roman co-emperor Lothar I, who had come to Rome to issue the Constitutio Romana that affirmed imperial sovereignty over Rome, demanded an oath of fealty from Eugenius, and vested papal election in the Roman clergy and nobles, subject to imperial confirmation.

Question: Clement XI: Answer: Clement XI sought to avert war between the Bourbons and the Habsburgs by mediation and to save Italy from inevitable calamity. He failed disastrously in both. French troops occupied Mantua, the key to upper Italy, but were ousted by the imperial general Prince Eugene of Savoy, launching the War of the Spanish Succession.

Question: Hormisdas: Answer: Hormisdas's great achievement was the reunion of the Eastern and Western churches, separated since the excommunication of Acacius in 484. After two unsuccessful attempts under the Byzantine emperor Anastasius I, Hormisdas settled the Acacian Schism with Anastasius’s successor, Justin I, and with Patriarch John of Cappadocia in 519 and thus reunited Constantinople and Rome.

Question: Boniface VI: Answer: Boniface VI either died of gout or was murdered by Stephen VI, who became the next pope. A central figure during a dark period in papal history (896–898) revolving around the death of Pope Formosus, Boniface was denounced at a Roman council held by Pope John IX in 898.

Question: Benedict VIII: Answer: Benedict VIII appears to have been more of a secular noble than a pope, spending much of his time on military expeditions. He restored papal authority in the Campagna and in Roman Tuscany by force of arms.

Question: Pius III: Answer: Pius III opposed the flagrant nepotism of Pope Alexander VI, after whose death Cesare Borgia, Alexander’s son, seized the Vatican with his troops in an attempt to control the conclave. Protected by the Romans, the cardinals gathered in the Church of the Minerva and on September 22, 1503, elected Francesco Todeschini Piccolomini, who took the name Pius III.

Question: Paul III: Answer: As a patron of the arts, Paul III restored the University of Rome, increased the subsidies and importance of the Vatican Library, and showed favor to theologians and canonists but did not neglect the fine arts. He cajoled Michelangelo into finishing the fresco “The Last Judgment” in the Sistine Chapel, decorating the Pauline Chapel, and completing the plans for the construction of the new St. Peter’s Basilica.

Question: Benedict XI: Answer: Benedict XI died suddenly in Perugia, and many at the time believed he was poisoned.

Question: Benedict IX (1st time): Answer: Benedict IX was pope three times, from 1032 to 1044, from April to May 1045, and from 1047 to 1048. The last of the popes from the powerful Tusculani family, he was notorious for selling the papacy and then reclaiming the office twice.

Question: Damasus II: Answer: Damasus II's brief reign, delayed by a rival claimant to the papal throne, occurred during a period when the German emperors and factions of the Roman nobility vied for control of the papacy.

Question: Leo XII: Answer: Under Leo XII, authoritarianism and aristocratic privilege were reinstated in the Papal States, a reaction that caused the bourgeoisie to resent a “government by priests.” Although he reduced expenditure, thus reducing taxation, the precarious economic situation remained unchanged. In doctrinal matters, Leo XII strove to prevent the infiltration of liberal ideas and to strengthen the efficiency of the Inquisition.

Question: Siricius: Answer: Siricius’s important decretal of 386 (written to Bishop Himerius of Tarragona), commanding celibacy for priests, was the first decree on this subject and has remained in force ever since the pontificate (440–461) of Pope Leo I the Great. Significantly, Siricius asserted papal authority by accompanying his decretals with threats of sanctions against those who contravened them; his letters designate the pope as a sovereign of the whole Western church, for which he makes laws.

Question: Eleutherius: Answer: During Eleutherius's papacy, the church was involved in a controversy over Montanism, a movement that arose in Asia Minor among Christians who believed that new spiritual revelations could be achieved through the ecstatic trances of their prophets.

Question: Benedict XVI: Answer: Benedict XVI overturned John Paul II’s reform of the papal election process and restored traditional practice when he declared that the election of a new pope requires a two-thirds majority of the cardinals attending the conclave. He was the first pope to resign since Gregory XII had done so in 1415.

Question: Gregory VIII: Answer: Elected with imperial support, Gregory VIII began reforms in the Curia and for the clergy as a whole and took immediate measures to restore Jerusalem to the Christians by initiating the Third Crusade but died during an effort to reconcile the rival Italian seaports of Pisa and Genoa in order to expedite shipments to the Holy Land.

Question: Martin V: Answer: As pope, Martin V faced enormous difficulties, for he had to restore the Western church, the papacy, and the Papal States. The Council of Constance accepted Martin V's proposal (January 1418) that ecclesiastics rule lands and cities belonging to the church, but he found it necessary to establish himself in these places diplomatically rather than forcibly.

Question: Alexander III: Answer: Alexander III was a vigorous exponent of papal authority, which he defended against challenges by the Holy Roman emperor Frederick I Barbarossa and King Henry II of England.

Question: Symmachus: Answer: Symmachus expelled the Manichaeans from Rome and burned their books. Symmanchus aided the poor, for whom he built refuges, and African Catholics, who were being persecuted by the Arians (followers of the heretical doctrine that the Son was neither equal with God the Father nor eternal), and he erected and restored several Roman churches, including the basilica of S. Agnese Fuori le Mura on the Via Aurelia.

Question: Sergius III: Answer: Sergius III held a synod that reaffirmed the “Cadaver Synod”—which had formally deposed the exhumed body of Pope Formosus—by once again invalidating all of Formosus’s ordinations, thus causing the church grave disorders.

Question: Boniface IV: Answer: Boniface IV converted the Roman Pantheon into the church of Santa Maria Rotonda (May 13, 609).

Question: Clement VII: Answer: Clement VII accelerated the breaking of the English church from Rome by finally pronouncing King Henry VIII’s marriage to Catherine of Aragon valid in 1533. His reign was also dominated by the spread of the Protestant Reformation and the conflict between France and the Holy Roman Empire.

Question: Pius VII: Answer: Pius VII's dramatic conflicts with Napoleon led to a restoration of the church after the armies of the French Revolution had devastated the papacy under Pius VI.

Question: Hippolytus: Answer: Hippolytus was the first antipope. He was a leader of the Roman church during the pontificate (c. 199–217) of St. Zephyrinus, whom he attacked as being a modalist (one who conceives that the entire Trinity dwells in Christ and who maintains that the names Father and Son are only different designations for the same subject).

Question: Theodore II: Answer: Theodore II was elected during one of the darkest periods in papal history, caused by the “Cadaver Synod” at which Pope Stephen VI had posthumously deposed and desecrated the disinterred corpse of Pope Formosus. Despite his brief reign, Theodore vindicated Formosus’s pontificate at a synod, after which he honorably buried the corpse—retrieved by Theodore’s predecessor Romanus—at St. Peter’s in Rome. Because of the intrigue in Rome over the Cadaver Synod and its consequences, some suspect that Theodore was murdered for his acts.

Question: Stephen V (or VI): Answer: Stephen’s pontificate witnessed the disintegration of the Carolingian empire and intermittent struggles for the Italian crown.

Question: Zosimus: Answer: Zosimus's brief but turbulent pontificate was embroiled in conflicts involving Gaul, Africa, and Pelagianism, a heretical doctrine that minimized the role of divine grace in humankind’s salvation.

Question: Lando: Answer: Lando reigned during one of the most difficult periods in papal history. The Holy See was then dominated by the relatives and dependents of the senior Theophylact of Rome.

Question: Marinus I: Answer: Marinus I was made bishop of Caere by Pope John VIII, who appointed him ambassador to Constantinople to negotiate the schism following following the condemnation of Patriarch Photius of Constantinople (869 or 870). Upon John’s assassination, Marinus was elected pope in December 882, the first bishop of another diocese to be elected bishop of Rome.

Question: Sergius I: Answer: With the help of King Cunipert of the Lombards, Sergius I healed the Aquileian schism, thus ending the entire controversy and unifying the church in Italy. He is also credited with introducing to the mass the Agnus Dei (“Lamb of God”—a liturgical chant preceding the eucharistic rite) and with instituting the procession for Candlemas, a festival of February 2 commemorating the Virgin Mary’s visit to Jerusalem to present Jesus to God as her firstborn.

Question: Pius VI: Answer: Pius VI's pontificate was the longest of the 18th century: it ran from 1775 to 1799. During his reign, religious orders came under increasing attack, and European powers disregarded papal interests. He lost the Papal States to Napoleon, and he died a prisoner in France.

Question: Eugenius IV: Answer: Eugenius IV's success at the Council of Ferrara–Florence enabled him to defy the Council of Basel (1431), thus ending the rump council and restoring papal sovereignty to the church. Eugenius IV's efforts to relieve Constantinople following the council were less successful.

Question: Paul V: Answer: Although Paul V censured Galileo and placed Copernicus’s treatise on the heliocentric theory of the solar system on the Index of Forbidden Books (Index Librorum Prohibitorum), in doctrinal matters he was surprisingly undogmatic. He encouraged missions, notably those in Latin America, and confirmed many new congregations and brotherhoods, including St. Philip Neri’s Oratorians (approved 1613), a congregation of secular priests.

Question: Zephyrinus: Answer: Zephyrinus failed to condemn Monarchianism or favor the Logos doctrine (emphasizing the distinction of the persons of the Trinity), of which Hippolytus was the passionate champion. Opposing Zephyrinus, Hippolytus thus started the first schism in the history of the Christian church.

Question: Boniface III: Answer: Boniface III was a deacon of the Roman church when Pope St. Gregory I the Great sent him in 603 as a legate to Constantinople, where he obtained from the Byzantine emperor Phocas an edict recognizing the see of Rome as the head of all the churches. As pope he convoked a synod to regulate papal elections.

Question: John XVIII (or XIX): Answer: More independent of the powerful Italian Crescentii family than John XVII, John XVIII (or XIX) eventually abdicated for unknown reasons and died shortly thereafter at the monastery of St. Paul Outside the Walls, Rome.

Question: Felix (V) (also called Amadeus VIII of Savoy): Answer: Amadeus VIII was count (1391–1416) and duke (1416–40) of Savoy, the first member of the house of Savoy to assume the title of duke. His 42-year reign saw the extension of his authority from Lake Neuchâtel on the north to the Ligurian coast, and under the title of Felix (V) he was an antipope for 10 years (1439–49).

Question: Victor III: Answer: Favored by the cardinals and his predecessor, Desiderius (Victor III) was chosen pope, but he declined the office, and the year 1085 passed without an election. On May 24, 1086, the cardinals proclaimed Victor III pope against his will, but, before his consecration was completed, he was driven from Rome by supporters of the Holy Roman emperor Henry IV, who had set up the antipope Clement III in 1084.

Question: Honorius (II): Answer: Aided by Lombard and German bishops, Empress Agnes—mother of the German King Henry IV (later emperor)—had Cadalus (Honorius II) chosen pope at Basel, Upper Burgundy, as Honorius II (October 28, 1061). Honorius II was installed at Rome by force of arms in April 1062; he is classed as an antipope.

Question: John XXIII: Answer: John XXIII was one of the most popular popes of all time. He inaugurated a new era in the history of the Roman Catholic Church by his openness to change (aggiornamento), shown especially in his convoking of the Second Vatican Council. He wrote several socially important encyclicals, most notably Pacem in Terris.

Question: Anacletus: Answer: According to St. Epiphanius and the priest Tyrannius Rufinus, Anacletus directed the Roman church with Linus, successor to St. Peter, during Peter’s lifetime.

Question: Sabinian: Answer: Under Pope Gregory I the Great, Sabinian served as papal ambassador at Constantinople, trying to reconcile the Roman church with Patriarch John IV the Faster, whose claim to the title of ecumenical patriarch was regarded by Gregory to be a threat to Christian unity.

Question: Paschal II: Answer: Although Paschal II fostered the First Crusade and followed Pope Gregory VII’s great policies of church reform, his pontificate was dominated by the Investiture Controversy—the long conflict between popes and secular rulers over control of ecclesiastical appointments. In 1107 settlements on the issue of lay investiture were made with kings Henry I of England and Philip I of France.

Question: Clement II: Answer: In 1047 Clement II convoked the Council of Rome that passed strong decrees against simony (i.e., the buying or selling of a church office) and began a period of reform that was carried on by his successors. His sudden death soon after returning from a trip to Germany was attributed to poisoning by supporters of the rival pope Benedict IX.

Question: Telesphorus: Answer: Telesphorus is considered the first pope after St. Peter to be martyred and is commemorated in the Greek and Roman churches.

Question: Gregory XVI: Answer: Gregory XVI was an inveterate opponent of democracy, liberalism, republicanism, and the separation of church and state. He opposed the rebellion of Roman Catholic Poles against the Russian tsar in 1830, and he did not favor the cause of Italian nationalism.

Question: Honorius I: Answer: Modeling his pontificate after Pope St. Gregory I the Great, Honorius I worked for the Christianization of the Anglo-Saxons, bestowing the pallium (i.e., the symbol of metropolitan jurisdiction) on Archbishop St. Honorius of Canterbury and Bishop St. Paulinus of York, inducing the Christian Celts to accept the Roman liturgy and date of Easter, and dispatching St. Birinus (later bishop of Dorchester) to mission in the ancient English kingdom of Wessex.

Question: Sixtus I: Answer: Probably born in Rome, Sixtus I ruled the church under the Roman emperor Hadrian.

Question: Sixtus V: Answer: By a bull of 1586 Sixtus V defined the Sacred College of Cardinals, setting the number of cardinals at no more than 70, a limit that was not exceeded until the pontificate of John XXIII (1958–63). The secretariat of state was reorganized, and in January 1588 the Curia’s entire administrative system was overhauled.

Question: Benedict (XIII) (at Avignon): Answer: Benedict (XIII) was antipope from 1394 to 1417. He reigned in Avignon, in opposition to the reigning popes in Rome, during the Western Schism (1378–1417).

Question: John Paul I: Answer: John Paul I's 33-day pontificate in 1978 was the shortest in modern times. He was the first pope to choose a double name and did so in commemoration of his two immediate predecessors, John XXIII and Paul VI. He was the first pope in centuries who refused to be crowned, opting instead for the simple pallium of an archbishop, and he was known affectionately as “the Smiling Pope” on account of the smile he often displayed in public.

Question: Anastasius (Anastasius the Librarian): Answer: Anastasius became papal librarian and disputed with the Greek Orthodox theologian Photius, patriarch of Constantinople, over the question of the Holy Spirit’s relationship within the Christian Trinity, a controversy crucial to Eastern and Western doctrinal differences leading to open schism.

Question: Anastasius I: Answer: Anastasius earned the praise of St. Jerome (Letter 127) for censuring (c. 400) the works of Origen, one of the most influential theologians of the early Greek church.

Question: Zacharias (Zachary): Answer: Zacharias’s action in the transference of the royal crown from the Merovingians to the house of Pippin (Carolingians) began a new era for church and state by establishing the Carolingian-papal alliance, which was to be of the greatest significance in future relations between pope and emperor. Zacharias is known especially in the East for his Greek translation of the Dialogues of Pope St. Gregory I the Great.

Question: Julius II: Answer: Julius II was the greatest art patron of the papal line and one of the most powerful rulers of his age. Although he led military efforts to prevent French domination of Italy, Julius II is most important for his close friendship with Michelangelo and for his patronage of other artists, including Bramante and Raphael.

Question: Boniface V: Answer: In endeavoring to apply canon law to civil law, Boniface V established the right of asylum. Boniface V also greatly helped the spread of Christianity in England, especially in Northumbria, by encouraging, through letters, the saintly missionaries evangelizing the Britons.

Innocent XIII recognized James (the Old Pretender) as the king of England and promised him subsidies conditional upon the reestablishment of Roman Catholicism in England.

Question: Eulalius: Answer: Both the pope, Boniface, and the antipope, Eulalius, were asked by Emperor Honorius to leave Rome pending a council’s decision, but Eulalius (the imperial favorite) imprudently returned to perform the Holy Week services at the Lateran.

Question: Nicholas III: Answer: In May 1280 Nicholas III arranged a treaty to terminate the claims of the sovereign dynasties—the Habsburgs and the Angevins—for the possession of Sicily. For his nepotism, Nicholas III appears in Hell in Dante’s Divine Comedy.

When Silverius refused to restore the patriarch of Constantinople, Anthimus, Theodora ordered the Byzantine general Belisarius to enter Rome (December 9, 536) and depose Silverius; she replaced him with the deacon Vigilius, then nuncio to Constantinople.

Question: Benedict IX (2nd time): Answer: In 1045 Benedict IX sold the papacy to his godfather, Giovanni Graziano, a Roman priest, who offered Benedict a pension.

Question: John VIII: Answer: John VIII solved a controversy over orthodoxy between the Holy See and the East by recognizing in 879 the heretofore condemned Photius as patriarch of Constantinople. Between 875 and 881 he fortified Rome against invaders and founded a papal navy. In 881 he crowned the Frankish king Charles III the Fat as Holy Roman emperor.

Question: John XV (or XVI): Answer: John XV (or XVI) carried out the first solemn canonization in history by papal decree. His election, August 985, came during one of the darkest periods in papal history, shadowed by the murders of the popes Benedict VI and John XIV by the antipope Boniface VII.

Question: Valentine: Answer: Beloved for his goodness and piety, Valentine was elected pope in August with lay participation, as mandated by the Constitutio Romana issued by the Carolingian co-emperor Lothar in 824. He died a month later, and little is known of his pontificate.

Question: Alexander VII: Answer: Alexander VII's pontificate was marked by several disputes. He confirmed the condemnation of Jansenism but supported the Jesuits, allowing them to use Chinese rites for their mission work in China.

Question: Stephen II (or III): Answer: Stephen II (or III) severed ties with the Byzantine Empire and thus became the first temporal sovereign of the newly founded Papal States.

Question: Anicetus: Answer: Possibly a Syrian, Anicetus labored to combat the errors of the heresies of Valentine and Marcion and to prevent heresies, working particularly against the Marcionites and gnostics.

Question: Liberius: Answer: Liberius was pope during the turbulence caused by the rise of Arianism—a heresy teaching that Christ was not truly divine but was rather a created being. Liberius was pope under the Arian Roman emperor Constantius II, who opposed both the Council of Nicaea (which had condemned Arianism) and Bishop Athanasius of Alexandria (who was Arianism’s most virulent opponent).

Question: Benedict XIII: Answer: Benedict XIII attacked the extravagance of the cardinals and the worldliness of ecclesiastics, but he had little effect. He continued the opposition of the papacy to Jansenism, a Roman Catholic movement of unorthodox tendencies that had begun in 17th-century France, although he allowed the Dominicans to preach the Augustinian doctrine of grace, which bordered on the Jansenist teaching.

Question: Adrian I: Answer: Adrian I's close relationship with the emperor Charlemagne symbolized the medieval ideal of union of church and state in a united Christendom.

Question: Leo I: Answer: Leo I further enhanced the prestige of the papacy and helped to place Western leadership in its hands by dealing with invading barbaric tribes. He persuaded the Huns, a nomadic people terrorizing northern Italy, not to attack Rome (452), and the Vandals, a Germanic people, not to sack Rome when they occupied it three years later.

Question: Pius X: Answer: Three aspects of Pius X's policy particularly aroused bitter controversy: the repression of Modernism, a contemporary intellectual movement seeking to reinterpret traditional Catholic teaching in the light of 19th-century philosophical, historical, and psychological theories; his reaction against Christian Democrats; and his attitude toward separation of church and state in France.

Question: Eugenius I: Answer: The Byzantine emperor Constans II Pogonatus urged Eugenius I to recognize Patriarch Peter of Constantinople, but Eugenius refused because Peter was a monothelite—i.e., advocator of a condemned doctrine proposing that Christ had only one will. Eugenius died before the emperor could exact revenge and was buried at St. Peter’s.

Question: Felix III (or II): Answer: Felix excommunicated Acacius, patriarch of Constantinople, in 484 for publishing with the emperor Zeno a document called the Henotikon, which appeared to favor monophysitism, a doctrine that had been denounced at the Council of Chalcedon (451).

Question: John XIX (or XX): Answer: On Easter 1027 John XIX (or XX) crowned as Holy Roman emperor the German king Conrad II, who controlled his ecclesiastical affairs except in Rome.

He was accused of violating canon law and of perjury, among other charges.

Question: Hilary: Answer: Hilary was elected pope in 461. His letters show him as a wise and zealous administrator, correcting abuses and solving disputes submitted from southern Gaul and Spain. His synod of 465 is the oldest Roman synod of which the acts survive.

While the Investiture Controversy raged between the German king Henry V (later Holy Roman emperor) and Pope Paschal II, the imperialist faction, under Werner, margrave of Ancona, elected Maginulfo as successor to the imperialist antipope Albert on November 18, 1105. He was the fourth in a line of antipopes set up against Paschal II.

Question: Gregory (VI): Answer: Compelled to flee Rome, Gregory, an antipope, went to Germany, where he appealed his case to King Henry II (later Holy Roman emperor). Henry forced him to relinquish his claim before he performed any official acts, thus restoring Benedict as pope.

Question: Lucius I: Answer: According to Bishop St. Cyprian of Carthage, Lucius continued the liberal policy Pope Cornelius had established toward apostates who renounced Christianity because of the persecution of the Roman emperor Decius.

Question: Paul VI: Answer: Paul VI worked to lessen the long-standing tensions between the church of Rome and other churches and even with those professing no religion at all. He sought out closer understanding with numerous religious leaders throughout the world, both Christian and non-Christian, placing more emphasis on those aspects that unite the churches than on those that divide.

Question: Cornelius: Answer: Cornelius’s pontificate was complicated by a schism, one cause of which was the self-appointment of the Roman priest Novatian as antipope (the second in papal history); another factor was the dispute over the church’s attitude toward Christian apostates.

Question: Stephen VIII (or IX): Answer: Stephen VIII (or IX) formally recognized Louis as king of France, threatening to excommunicate those who rebelled against him.

Question: Marinus II: Answer: The pontificate of Marinus II was dictated by a Roman senator, Alberic, leaving Marinus little room for political or economic innovation. Marinus managed, however, to work for church reform, contributing mainly to discipline and monasticism.

Question: John VI: Answer: When the Byzantine commander Theophylactus invaded the Italian mainland from Sicily, John VI protected him from the local reaction; and, when Gisulfo, the Lombard duke of Benevento, crossed the southern frontier of Roman territory, John ransomed captives and bribed him to withdraw. In his only extant letter, John ordered the restoration of the deposed bishop St. Wilfrid of York.

Question: Leo III: Answer: At a large gathering in 800 in St. Peter’s Basilica for the consecration of Charlemagne’s son (Louis I the Pious) as king, Leo III suddenly crowned Charlemagne as emperor. By this act, Leo III obliterated his earlier humiliation and established the legal precedent that only the pope could confer the imperial crown.

Question: Adrian V: Answer: Elected as successor to Innocent V on July 11, Adrian V died a little more than a month later, having, however, revoked the stern conclave regulations of Pope Gregory X. Adrian V died before he was ordained a priest or consecrated. Dante in his Purgatory (XIX, 97–126) portrays him as lamenting his avarice and acknowledging “how the great mantle weighs” and “so justice here holds us close.”

He concluded the Treaty of Constance (1153) with the Holy Roman emperor Frederick I Barbarossa, fixing conditions for his imperial coronation, but the pope died before Frederick could come to Italy.

Question: Gregory I: Answer: For Gregory I, the church and its sacraments provided a safe path to salvation in a troubled world, and the importance he placed on the Eucharist defined the medieval church.

Question: Benedict X: Answer: Benedict X's expulsion from the papal throne, on which he had been placed through the efforts of the powerful Tusculani family of Rome, was followed by a reform in the law governing papal elections.

Question: Deusdedit (also called Adeodatus I): Answer: Deusdedit's pontificate is chiefly noteworthy for an unsuccessful resumption of the Byzantine war against the Lombards in Italy and for a reversal of the policy of Popes Gregory I and Boniface IV, who favored monks over the secular clergy. Deusdetit, instead, proved partial to the diocesan, or secular, clergy.

Question: Felix I: Answer: Felix I was the author of an important dogmatic letter on the unity of Christ’s Person.

Question: Pius XII: Answer: During Pius XII's reign as pope, the papacy confronted the ravages of World War II (1939–45); the abuses of the Nazi, fascist, and Soviet regimes; the horror of the Holocaust; the challenge of postwar reconstruction; and the threat of communism and the Cold War. Deemed an ascetic and “saint of God” by his admirers, Pius XII was criticized by others for his alleged “public silence” in the face of genocide and his apparently contradictory policies of impartiality during World War II but fervent anticommunism during the postwar period.

Question: John X: Answer: When the Holy Roman emperor Berengar was assassinated in 924, John X allied with King Hugh of Italy in order to distance himself from Rome’s noble families.
