Henry IV, also known as Henry Bolingbroke, was King of England from 1399 to 1413. Henry was the son of John of Gaunt, Duke of Lancaster, and Blanche of Lancaster.
John of Gaunt, Duke of Lancaster was an English royal prince, military leader, and statesman. He was the fourth son of King Edward III of England, and the father of King Henry IV. Because of Gaunt's royal origin, advantageous marriages, and some generous land grants, he was one of the richest men of his era, and was an influential figure during the reigns of both his father and his nephew, Richard II. As Duke of Lancaster, he is the founder of the royal House of Lancaster, whose members would ascend the throne after his death. His birthplace, Ghent in Flanders, then known in English as Gaunt, was the origin of his name.
John Beaufort, 1st Marquess of Somerset and 1st Marquess of Dorset, later only 1st Earl of Somerset, was an English nobleman and politician. He was the first of the four children of John of Gaunt (1340–1399) by his mistress Katherine Swynford, whom he later married in 1396.
The House of Lancaster was a cadet branch of the royal House of Plantagenet. The first house was created when King Henry III of England created the Earldom of Lancaster—from which the house was named—for his second son Edmund Crouchback in 1267. Edmund had already been created Earl of Leicester in 1265 and was granted the lands and privileges of Simon de Montfort, 6th Earl of Leicester, after de Montfort's death and attainder at the end of the Second Barons' War. When Edmund's son Thomas, 2nd Earl of Lancaster, inherited his father-in-law's estates and title of Earl of Lincoln he became at a stroke the most powerful nobleman in England, with lands throughout the kingdom and the ability to raise vast private armies to wield power at national and local levels. This brought him—and Henry, his younger brother—into conflict with their cousin King Edward II, leading to Thomas's execution. Henry inherited Thomas's titles and he and his son, who was also called Henry, gave loyal service to Edward's son King Edward III.
The House of York was a cadet branch of the English royal House of Plantagenet. Three of its members became kings of England in the late 15th century. The House of York descended in the male line from Edmund of Langley, 1st Duke of York, the fourth surviving son of Edward III. In time, it also represented Edward III's senior line, when an heir of York married the heiress-descendant of Lionel, Duke of Clarence, Edward III's second surviving son. It is based on these descents that they claimed the English crown. Compared with its rival, the House of Lancaster, it had a superior claim to the throne of England according to cognatic primogeniture, but an inferior claim according to agnatic primogeniture. The reign of this dynasty ended with the death of Richard III of England at the Battle of Bosworth Field in 1485. It became extinct in the male line with the death of Edward Plantagenet, 17th Earl of Warwick, in 1499.
Lionel of Antwerp, Duke of Clarence,, was an English prince, Earl of Ulster jure uxoris from 1347, Duke of Clarence from 1362, Guardian of England in 1345-1346, Lord Lieutenant of Ireland in 1361-1366, Knight of the Garter from 1361, second surviving son of King Edward III of England and Philippa of Hainault. He was named after his birthplace, at Antwerp in the Duchy of Brabant.
Edmund of Langley, 1st Duke of York was the fourth surviving son of King Edward III of England and Philippa of Hainault. Like many medieval English princes, Edmund gained his nickname from his birthplace: Kings Langley Palace in Hertfordshire. He was the founder of the House of York, but it was through the marriage of his younger son, Richard of Conisburgh, 3rd Earl of Cambridge, to Anne de Mortimer, great-granddaughter of Edmund's elder brother Lionel of Antwerp, 1st Duke of Clarence, that the House of York made its claim to the English throne in the Wars of the Roses. The other party in the Wars of the Roses, the incumbent House of Lancaster, was formed from descendants of Edmund's elder brother John of Gaunt, 1st Duke of Lancaster, Edward III's third son.
Edmund Mortimer, 5th Earl of March, 7th Earl of Ulster, was an English nobleman and a potential claimant to the throne of England. A great-great-grandson of King Edward III of England, he was heir presumptive to King Richard II of England when he was deposed in favour of Henry IV. Edmund Mortimer's claim to the throne was the basis of rebellions and plots against Henry IV and his son Henry V, and was later taken up by the House of York in the Wars of the Roses, though Mortimer himself was an important and loyal vassal of Henry V and Henry VI. Edmund was the last Earl of March of the Mortimer family.
John Holland, 1st Duke of Exeter, 1st Earl of Huntingdon, KG, of Dartington Hall in Devon, was a half-brother of King Richard II (1377–1399), to whom he remained strongly loyal. He is primarily remembered for being suspected of assisting in the downfall of King Richard's uncle Thomas of Woodstock, 1st Duke of Gloucester (1355–1397) and then for conspiring against King Richard's first cousin and eventual deposer, Henry Bolingbroke, later King Henry IV (1399–1413).
Edmund Mortimer, 3rd Earl of March and Earl of Ulster was an English magnate who was appointed Lieutenant of Ireland but died after only two years in the post.
Roger de Mortimer, 4th Earl of March, 6th Earl of Ulster was an English nobleman. He was considered the heir presumptive to King Richard II, his mother's first cousin, as being a great-grandson of King Edward III.
The House of Plantagenet was a royal house which originated in the French County of Anjou. The name Plantagenet is used by modern historians to identify four distinct royal houses: the Angevins, who were also counts of Anjou; the main line of the Plantagenets following the loss of Anjou; and the Houses of Lancaster and York, two of the Plantagenets cadet branches. The family held the English throne from 1154, with the accession of Henry II, until 1485, when Richard III died.
Henry Scrope, 3rd Baron Scrope of Masham KG, also known in older sources as Lord Scrope was a favourite of Henry V, who performed many diplomatic missions. He was beheaded for his involvement in the notional Southampton Plot to assassinate the king. Some historians believe that the charge was trumped-up to punish him for other acts of disloyalty, and that there may never have been such a plot.
Thomas Chaucer was an English courtier and politician. The son of the poet Geoffrey Chaucer and his wife Philippa Roet, Thomas was linked socially and by family to senior members of the English nobility, though he was himself a commoner. Elected fifteen times to the Parliament of England, he was Speaker of the House of Commons for five parliaments in the early 15th century.
The Southampton Plot was a conspiracy to depose King Henry V of England, revealed in 1415 just as the king was about to sail on campaign to France as part of the Hundred Years' War. The plan was to replace him with Edmund Mortimer, 5th Earl of March.
The House of Beaufort is an English noble and quasi-royal family which originated in the fourteenth century as the legitimated issue of John of Gaunt, 1st Duke of Lancaster by Katherine Swynford. Gaunt and Swynford had four children: John Beaufort, 1st Earl of Somerset (1373–1410); Cardinal Henry Beaufort (1375–1447), Bishop of Winchester; Thomas Beaufort, 1st Duke of Exeter (1377–1426) and Joan Beaufort, Countess of Westmorland (1379–1440). When Gaunt finally married Swynford as his third wife in 1396, the Beauforts were legitimized by Pope Boniface IX and by royal proclamation of the reigning monarch King Richard II the following year.
Isabella of Castile, Duchess of York was the daughter of King Peter and his mistress María de Padilla. She accompanied her elder sister, Constance, to England after Constance's marriage to John of Gaunt, 1st Duke of Lancaster, and married Gaunt's younger brother, Edmund of Langley, 1st Duke of York.
British history provides several opportunities for alternative claimants to the English and later British Crown to arise, and historical scholars have on occasion traced to present times the heirs of those alternative claims.
Alianore Holland, Countess of March was the eldest daughter of Thomas Holland, 2nd Earl of Kent, and the wife of Roger Mortimer, 4th Earl of March, heir presumptive to her uncle, King Richard II. Through her daughter, Anne Mortimer, she was the great-grandmother of the Yorkist kings Edward IV and Richard III. She was governess to Richard II's wife, Isabella of Valois.
Sir Edmund Mortimer IV was an English nobleman and landowner who played a part in the rebellions of the Welsh leader Owain Glyndŵr and of the Percy family against King Henry IV, at the beginning of the 15th century. He perished at the siege of Harlech as part of these conflicts. He was related to many members of the English royal family through his mother, Princess Philippa, Countess of Ulster, who was a granddaughter of King Edward of Windsor.
