Kingdom of the Burgundians in the context of "Theodoric II"

The Burgundians (Latin: Burgundiones or less commonly Burgundii) were a Germanic people of the Roman imperial era, who established the powerful Kingdom of the Burgundians within the Roman empire, in what is now western Switzerland and south-eastern France. This kingdom is the source of much later names related to the region of Burgundy, including medieval entities such as the Duchy of Burgundy.

In earlier periods, peoples with the same name were reported by Roman sources to have lived in different parts of what is now Germany and Poland, and there are believed to be connections between at least some of these groups. For one thing, the kingdom's core group were followers of the Gibichung dynasty, who had previously led them as foederati in Roman territory on the Rhine border, probably near Worms in present day Germany. They left the Rhine after the Romans and their Hun allies killed many of the Burgundians along with their king Gundahar in 436, accusing them of rebellion. The death of Gundahar at the hands of the Huns became a central theme in medieval Germanic heroic legend, including the Nibelungenlied (where he is “Günther”) and the Völsunga saga (where he is “Gunnar”). After the remnants resettled in Sapaudia near Lake Geneva in about 443, their territory expanded to include Lyon as a new capital. The entire kingdom was incorporated into the Frankish empire in 534.

The Franks, Germanic peoples that invaded the Western Roman Empire in the 5th century, were first led by individuals called dukes and reguli. The earliest group of Franks that rose to prominence was the Salian Merovingians, who conquered most of Roman Gaul, as well as the Gaulish territory of the Visigothic Kingdom, following the Battle of Vouillé in 507 AD.

The sons of Clovis I, the first King of the Franks, conquered the Burgundian and the Alamanni Kingdoms. They acquired Provence, and went on to make the peoples of the Bavarii and Thuringii their clients. The Merovingians were later replaced by the new Carolingian dynasty in the 8th century. By the late 10th century, the Carolingians themselves had been replaced throughout much of their realm by other dynasties.

The Helvetii (Ancient Greek: Ἐλουήτιοι, Latin: Helvētiī [hɛɫˈweːti.iː], Gaulish: *Heluētī), anglicized as Helvetians, were a Celtic tribe or tribal confederation occupying most of the Swiss plateau at the time of their contact with the Roman Republic in the 1st century BC. According to Julius Caesar, the Helvetians were divided into four subgroups or pagi. Of these, Caesar names only the Verbigeni and the Tigurini, while Posidonius mentions the Tigurini and the Tougeni (Τωυγενοί). They feature prominently in the Commentaries on the Gallic War, with their failed migration attempt to southwestern Gaul (58 BC) serving as a catalyst for Caesar's conquest of Gaul.

The Helvetians were subjugated after 52 BC, and under Augustus, Celtic oppida, such as Vindonissa or Basilea, were re-purposed as garrisons. In AD 68, a Helvetian uprising was crushed by Aulus Caecina Alienus.The Swiss plateau was at first incorporated into the Roman province of Gallia Belgica (22 BC), later into Germania Superior (AD 83).The Helvetians, like the rest of Gaul, were largely Romanized by the 2nd century. In the later 3rd century, Roman control over the region waned, and the Swiss plateau was exposed to the invading Alemanni. The Alemanni and Burgundians established permanent settlements in the Swiss plateau in the 5th and 6th centuries, resulting in the early medieval territories of Alemannia (Swabia) and Upper Burgundy. The Helvetii were largely assimilated by their new rulers, contributing to the ethnogenesis of modern Swiss people.

Burgundy (/ˈbɜːrɡəndi/ BUR-gən-dee, French: Bourgogne [buʁɡɔɲ] ; Burgundian: Bregogne) is a historical region in France, encompassing the territory of the former administrative region of the same name, that existed from 1982 to 2015, and was merged since 1 January 2016 into the newly created administrative region of Bourgogne-Franche-Comté, encompassing its western half. In historical terms, that region was formed as the Duchy of Burgundy, which existed between the 10th and the 18th century. During the late medieval and early modern periods, the region was of great political importance, being the core of the Valois-Burgundian State, and also becoming a focal point of diplomacy and courtly culture that set the fashion for European royal houses and their courts. The regional capital, Dijon, was wealthy and powerful, being a major European centre of art and science, and of Western Monasticism.

The modern Burgundy encompasses only the north-western parts of the ancient Kingdom of the Burgundians, that had much wider territorial scope. In 843, under the Treaty of Verdun, old Burgundian lands were divided, with all of north-western regions being assigned to the West Frankish Kingdom. Since the beginning of the 10th century, those regions were organized as the Duchy of Burgundy, remaining under the sovereignty of the Kingdom of France. Since 1004, the House of Burgundy, a cadet branch of the French royal House of Capet, ruled over the Duchy, that roughly conformed to the borders and territories of the later administrative region of Burgundy. Upon the extinction of the Burgundian male line the duchy reverted to the King of France and the House of Valois.

Worms (/vɔːrmz, wɜːrmz/; German pronunciation: [vɔʁms] ) is a city in Rhineland-Palatinate, Germany, situated on the Upper Rhine about 60 km (40 mi) south-southwest of Frankfurt am Main. It had about 84,646 inhabitants as of 2022.

A pre-Roman foundation, Worms is one of the oldest cities in northern Europe. It was the capital of the Kingdom of the Burgundians in the early fifth century, hence is the scene of the medieval legends referring to this period, notably the first part of the Nibelungenlied.

The term Nibelung (German) or Niflungr (Old Norse) is a personal or clan name with several competing and contradictory uses in Germanic heroic legend. It has an unclear etymology, but is often connected to the root Nebel, meaning mist. The term in its various meanings gives its name to the Middle High German heroic epic the Nibelungenlied.

The most widespread use of Nibelung is used to denote the Burgundian royal house, also known as the Gibichungs (German) or Gjúkingar (Old Norse). A group of royal brothers led by king Gunther or Gunnar, the Gibichungs are responsible for the death of the hero Siegfried or Sigurd and are later destroyed at the court of Attila the Hun (called Etzel in German and Atli in Old Norse). This is the only use of the term attested in the Old Norse legends.

Gundaharius or Gundahar (died 437), better known by his legendary names Gunther (Middle High German: Gunther) or Gunnar (Old Norse: Gunnarr), was a historical King of the Burgundians in the early 5th century. Gundahar is attested as ruling his people shortly after they crossed the Rhine into Roman Gaul. He was involved in the campaigns of the failed Roman usurper Jovinus before the latter's defeat, after which he was settled on the left bank of the Rhine as a Roman ally. In 436, Gundahar launched an attack from his kingdom on the Roman province of Belgica Prima. He was defeated by the Roman general Flavius Aetius, who destroyed Gundahar's kingdom with the help of Hunnish mercenaries the following year, resulting in Gundahar's death.

The historical Gundahar's death became the basis for a tradition in Germanic heroic legend in which the legendary Gunther met his death at the court of Attila the Hun (Etzel/Atli). The character also became attached to other legends: most notably he is associated with Siegfried/Sigurd and Brunhild, and is implicated in Sigurd's murder. He also appears as an adversary in the legend of Walter of Aquitaine. It is generally assumed that Gunther's involvement in these other legends, in which he plays a secondary or antagonistic role, is a later development. Gunther's importance in the story of the destruction of the Burgundians also waned with time.
