The Marcomanni were a Germanic people that established a powerful kingdom north of the Danube, somewhere near modern Bohemia, during the peak of power of the nearby Roman Empire. According to Tacitus and Strabo, they were Suebian.

The Suebi were a large group of Germanic peoples originally from the Elbe river region in what is now Germany and the Czech Republic. In the early Roman era they included many peoples with their own names such as the Marcomanni, Quadi, Hermunduri, Semnones, and Lombards. New groupings formed later such as the Alamanni and Bavarians and two kingdoms in the Migration Period were simply referred to as Suebian.

The Vandals were a Germanic people who first inhabited what is now southern Poland. They established Vandal kingdoms on the Iberian Peninsula, Mediterranean islands, and North Africa in the fifth century.

The Cherusci were an early Germanic people that inhabited parts of the plains and forests of northwestern Germany, in the area possibly near present-day Hanover, during the first centuries BC and AD. Ethnically, Pliny the Elder groups them with their neighbours, the Suebi and Chatti, as well as the Hermunduri, as Hermiones, one of the Germanic groupings said to descend from an ancestor named Mannus. They led an important war against the Roman Empire. Subsequently, they were probably absorbed into the late classical Germanic tribal groups such as the Saxons, Thuringians, Franks, Bavarians and Allemanni.

The Gallic Wars were waged between 58 BC and 50 BC by the Roman general Julius Caesar against the peoples of Gaul. Gallic, Germanic, and Britonic tribes fought to defend their homelands against an aggressive Roman campaign. The Wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. Though the Gallic military was as strong as the Romans, the Gallic tribes' internal divisions eased victory for Caesar. Gallic chieftain Vercingetorix's attempt to unite the Gauls under a single banner came too late. Caesar portrayed the invasion as being a preemptive and defensive action, but historians agree that he fought the Wars primarily to boost his political career and to pay off his debts. Still, Gaul was of significant military importance to the Romans. Native tribes in the region, both Gallic and Germanic, had attacked Rome several times. Conquering Gaul allowed Rome to secure the natural border of the river Rhine.

The Teutons were an ancient northern European tribe mentioned by Roman authors. The Teutons are best known for their participation, together with the Cimbri and other groups, in the Cimbrian War with the Roman Republic in the late second century BC.

The Ubii were a Germanic tribe first encountered dwelling on the east bank of the Rhine in the time of Julius Caesar, who formed an alliance with them in 55 BC in order to launch attacks across the river. They were transported in 39 BC by Marcus Vipsanius Agrippa to the west bank, apparently at their own request, as they feared the incursions of their neighbors, the Chatti.

The Ampsivarii, sometimes referenced by modern writers as Ampsivari, were a Germanic tribe mentioned by ancient authors.

The Belgae were a large confederation of tribes living in northern Gaul, between the English Channel, the west bank of the Rhine, and the northern bank of the river Seine, from at least the third century BC. They were discussed in depth by Julius Caesar in his account of his wars in Gaul. Some peoples in Britain were also called Belgae and O'Rahilly equated them with the Fir Bolg in Ireland. The Belgae gave their name to the Roman province of Gallia Belgica and, much later, to the modern country of Belgium; today "Belgae" is also Latin for "Belgians".

The Istaevones were a Germanic group of tribes living near the banks of the Rhine during the Roman Empire which reportedly shared a common culture and origin. The Istaevones were contrasted to neighbouring groups, the Ingaevones on the North Sea coast, and the Herminones, living inland of these groups.

The Battle of Vercellae, or Battle of the Raudine Plain, was fought on 30 July 101 BC on a plain near Vercellae in Gallia Cisalpina. A Germanic-Celtic confederation under the command of the Cimbric king Boiorix was defeated by a Roman army under the joint command of the consul Gaius Marius and the proconsul Quintus Lutatius Catulus. The battle marked the end of the Germanic threat to the Roman Republic.

The Vangiones appear first in history as an ancient Germanic tribe of unknown provenance. They threw in their lot with Ariovistus in his bid of 58 BC to invade Gaul through the Doubs river valley and lost to Julius Caesar in a battle probably near Belfort. After some Celts evacuated the region in fear of the Suebi, the Vangiones, who had made a Roman peace, were allowed to settle among the Mediomatrici in northern Alsace.. They gradually assumed control of the Celtic city of Burbetomagus, later Worms.

The Marcomannic Wars were a series of wars lasting from about 166 AD until 180. These wars pitted the Roman Empire against, principally, the Germanic Marcomanni and Quadi and the Sarmatian Iazyges; there were related conflicts with several other Germanic, Sarmatian and Gothic peoples along both sides of the whole length of the Roman Empire's northeastern European border, the river Danube.

The Taifals or Tayfals were a people group of Germanic or Sarmatian origin, first documented north of the lower Danube in the mid third century AD. They experienced an unsettled and fragmented history, for the most part in association with various Gothic peoples, and alternately fighting against or for the Romans. In the late fourth century some Taifali were settled within the Roman Empire, notably in western Gaul in the modern province of Poitou. They subsequently supplied mounted units to the Roman army and continued to be a significant source of cavalry for early Merovingian armies. By the sixth century their region of western Gaul had acquired a distinct identity as Thifalia.

The Tulingi were a small tribe closely allied to the Celtic Helvetii in the time of Julius Caesar's conquest of Gaul. Their location is unknown; their language and descent are uncertain. From their close cooperation with the Helvetii it can be deduced that they were probably neighbours of the latter. At the Battle of Bibracte in 58 BCE, they were, with the Boii and a few other smaller tribes, allies of the Helvetii against the Roman legions of Caesar.
