Roman military settlement The only source to date the Burgundian settlement near Lake Geneva is the unreliable
Gallic Chronicle of 452, which records that in 443 “Sapaudia was given to the remainders of the Burgundians to be divided with the indigenous inhabitants.” Its exact boundaries are uncertain, but it lay in the Roman province of
Maxima Sequania and included
Geneva, and
Neuchâtel. Historian
Ian N. Wood notes that this first settlement didn’t draw much attention from contemporaries and probably didn’t involve a large migration of Burgundians. According to him the Burgundians settled in Sapaudia can be seen as a Roman military unit. The first kings were most importantly military officials of the Roman empire. Their non-Roman followers were not all Burgundian, and non-Burgundians joined over time. In Wood’s opinion, a true Burgundian “kingdom” which was not based upon a Roman military office only emerged between 474 and 494. After the accession of Julius Nepos in 474 King Gundobad could no longer claim to represent the western imperial court., The
Lex Burgundionum law code, issued under Gundobad, nonetheless invokes earlier kings back to Gundahar, and beyond. One clause confirms the freedom of persons proved to have been freeborn under earlier “predecessors of royal memory” including not only his father and uncle (Gundioc and Chilperic) but also “
Gibica,
Gundomar,
Gislahar, and Gundahar”. Another clause voids all unresolved Burgundian legal cases before the Battle of the Mauriac Plains (Catalaunian Plains) in 451. Whether or not Gundioc was the son, or even descendant, of Gundahar, is not certain.
Gregory of Tours reported that Gundioc ("Gundevech") was a descendant of the
Tervingian Goth
Athanaric.
Battle of the Catalaunian Plains The 451 Battle of the Catalaunian Plains was a decisive turning point for the Burgundians, comparable to its impact on the
Visigoths. The
Lex Burgundionum, made later, during the time of Gundobad, voids all unresolved Burgundian legal cases prior to the battle. Burgundians and other barbarian kingdoms from Gaul fought for Rome under Aetius, put Attila the Hun and his allies to flight, but the Visigothic king
Theodoric I was killed during the battle, and
Thorismund his son followed the advice of Aetius not to pursue. Near contemporary
Sidonius Apollinaris reported that Burgundians also fought on the Hun side, who may have lived east of the Rhine outside Roman control.
Imperial politics Around the time of the battle — “or probably slightly earlier” — Gundioc cemented ties with the future western power-broker Ricimer by marrying his sister, a link that helps explain later Burgundian–imperial coordination. Attila died in 453, and Aetius in 454, as well as emperor
Valentinian III who assassinated him. Also in 454, the
Continuatio Prosperi Havniensis surprsingly reports that Burgundians scattered throughout Gaul () were driven back () by the
Gepids. The Gepids had been one of the most important peoples allied with Attila in his attack on Gaul, but their kingdom was based far away in the area of what is now
Romania, so modern scholars suspect either an error in the text, or missing information needed to interpret it properly.
Petronius Maximus was killed in 455 after less than three months in power, and soon afterwards
Rome was sacked by the Vandals based in North Africa. On 9 July 455
Theodoric II, the new king of the
Visigoths, acclaimed the
Gallo-Roman noble
Avitus as the new emperor, who was at the Visigothic city of
Toulouse at the time, sent by Petronius on an embassy to the Visigoths. In a poem dedicated to Avitus, referring to the time of the sacking, Sidonius implicates an unnamed Burgundian for leading Avitus to be angry at Petronius about the sack. In 456 the Burgundian kings Gundioc and Chilperic joined Theoderic II on a successful Roman-backed campaign against the
Kingdom of the Suebi in
Hispania. This is the first time that any of the royal family in Sapaudia are mentioned by name in contemporary records. However, in October 456 Avitus was overthrown as emperor by
Majorian and Ricimer, who became the new emperor and
magister militum. Soon after this in 456,
Marius Aventicensis reported that the Burgundians "occupied part of Gaul and divided the lands with the Gallic senators". This may have been based on military agreements already made by Avitus, implied by the Burgundian participation in the Suebian campaign. It is also possible that the Gallo-Roman nobility (the senators) didn't accept the new regime in Rome. The military aspect of the new arrangement is apparently reflected in 457, when the Burgundian soldiers return from Hispania, and some may have now been garrisoned in Lyon. The
Continuatio Prosperi Havniensis reported that "Gundioc, king of the Burgundians, with his people and all his forces, entered Gaul to settle", with Gothic approval and friendship. According to Wood: "for the first time a formative role in his people’s development is attributed to a member of the Gibichung family". In 458 Marjorian invaded Gaul without Ricimer, pushing Theoderic II out of Septimania, and occupied the discontented city of Lyon, apparently Burgundian forces from the city. He was murdered by Ricimer in 461. After this, political leadership in the western empire was dominated by the patrician Ricimer, brother-in-law of Gundioc. Under Ricimer’s influence, Burgundian control expanded steadily down the Rhône valley. Lyon was taken from imperial control during the later 460s, and the Burgundians also pushed south towards the
Drôme. By this point, Gundioc was recognised not only as king but also as
magister militum for Gaul, holding formal Roman military authority. In 468, the
praetorian prefect of Gaul,
Arvandus, notoriously suggested to the Visigothic king
Euric that Gaul be divided between Goths and Burgundians — a proposal that modern historians generally see as reflecting the strength of these two federate kingdoms relative to the Italian government. Gundioc died around 470, succeeded by his brother Chilperic I. When Visigothic forces moved up the lower Rhône in 471, Chilperic repelled them, beginning a period of intermittent Burgundian–Gothic hostility. Fighting also continued on the northern frontier: by the mid-470s Burgundians were active against the Alemanni in the Langres–Besançon–Jura region, eventually incorporating much of Maxima Sequanorum and parts of Lugdunensis I into their sphere. In 472, Ricimer–who was by now the son-in-law of the new Western Emperor
Anthemius–was plotting with Gundobad to kill his father-in-law; Gundobad beheaded the emperor (apparently personally). Ricimer then appointed
Olybrius; both died, surprisingly of natural causes, within a few months. Gundobad seems then to have succeeded his uncle as Patrician and king-maker, and raised
Glycerius to the throne. In 474, Burgundian influence over the empire seems to have ended. Glycerius was deposed in favour of
Julius Nepos, and Gundobad returned to Burgundy. At this time or shortly afterwards, the Burgundian kingdom was divided among Gundobad and his brothers, Godigisel, Chilperic II, and Gundomar I.
Independent kingdom Chilperic I still held the Roman office of
magister militum in Gaul when Gundobad returned from Italy in the mid-470s. Gundobad may have based himself initially at Geneva rather than Lyon, perhaps for strategic reasons given Alpine deployments of the emperor in Italy, Julius Nepos.
Gregory of Tours later claimed that Gundobad killed his uncle, but the evidence is ambiguous. By about 480 Chilperic was dead, and Gundobad became the principal king. In Burgundian fashion he shared power with three brothers:
Godegisel at Geneva,
Chilperic II at
Vienne, Isère, and
Godomar I at
Valence, Drôme. In 500 Godegisel allied with the Frankish king
Clovis I—who had married his niece
Clotilde—and turned on Gundobad during a battle near
Dijon. Gundobad was defeated and retreated to
Avignon. Clovis withdrew, leaving Frankish troops to protect Godegisel in Vienne; with Visigothic help, however, Gundobad retook the city in 501, killing his brother and the Frankish garrison. After this
civil war, Gundobad rebuilt relations with Clovis, united the kingdom under his sole rule, were allies of the Franks during their 507
Battle of Vouillé campaign against the Visigoths. After the Visigothic defeat the Burgundians took Gothic territory in
Provence and raided as far as Toulouse and
Barcelona. Ostrogothic intervention in 508–509 stripped them of conquests in southern Gaul, and a new peace was arranged fixing the
Durance as the southern frontier. The Burgundians emerged almost empty-handed, while the Franks and Ostrogoths made substantial gains. Gundobad died in 516 and was succeeded by his son Sigismund, who had already ruled from Geneva since about 501. Sigismund converted from
Arianism to
Catholicism, the faith of his mother, before his father died, and cultivated ties with the Catholic episcopate, notably
Avitus of Vienne. His foundation of the
Abbey of Saint-Maurice d'Agaune in 515 became a central royal cult site. With the last Western emperors now dead, Sigismund, like his father, kept contact with the eastern Emperors in
Constantinople. He was honored with the Roman dignity of , which his father had held. Tensions with the Arian Visigoths and
Ostrogoths who now ruled Italy rose when, after the death of his first wife Ariagne, a daughter of
Theoderic the Great, Sigismund executed his own son Sigerich in 522. In 523–524, conflict with the Ostrogoths and the sons of Clovis brought a two-front invasion. Sigismund was captured by the Franks and executed with his family; his brother Godomar II rallied the Burgundians and defeated the Franks at the
Battle of Vézeronce in 524. Godomar’s reign lasted a decade, marked by renewed alliance with the Ostrogoths and the recovery of territory south of the Durance. In 532–534, however, a coordinated Frankish campaign ended in Burgundian defeat near Autun. The kingdom was partitioned among the victors, becoming a Frankish sub-kingdom while retaining a distinct Burgundian identity. ==List of kings==
