Theodoric II (c. 422 – early 466) was king of the Aquitanian Goths between 453 and 466. From his reign it is known that he was a faithful ally of the Romans in the beginning. His Gothic warriors frequently took action as auxiliary forces of the Roman army. Especially with the Roman emperor Avitus he was on good terms, but after the death of Avitus in 456 his attitude changed and he behaved more and more independently.
Septimania is a historical region in modern-day southern France. It referred to the western part of the Roman province of Gallia Narbonensis that passed to the control of the Visigoths in 462, when Septimania was ceded to their king, Theodoric II. During the Early Middle Ages, the region was variously known as Gallia Narbonensis, Gallia, or Narbonensis. The territory of Septimania roughly corresponds with the modern French former administrative region of Languedoc-Roussillon that merged into the new administrative region of Occitanie. In the Visigothic Kingdom, which became centred on Toledo by the end of the reign of Leovigild, Septimania was both an administrative province of the central royal government and an ecclesiastical province whose metropolitan was the Archbishop of Narbonne. Originally, the Goths may have maintained their hold on the Albigeois, but if so it was conquered by the time of Chilperic I. There is archaeological evidence that some enclaves of Visigothic population remained in Frankish Gaul, near the Septimanian border, after 507.
The region of Septimania was invaded by the Andalusian Muslims in 719, renamed as Arbūnah and turned into a military base for future operations by the Andalusian military commanders. It passed briefly to the Emirate of Córdoba, which had been expanding from the south during the same century, before its subsequent conquest by the Christian Franks in 759, who by the end of the 9th century renamed it as Gothia or the Gothic March (Marca Gothica). Eventually, the Christian Franks chased the Muslim Arabs and Berbers away from Septimania and conquered Narbonne in 759, and the Carolingian king Pepin the Short came up reinforced. Septimania became a march of the Carolingian Empire and then West Francia down to the 13th century, though it was culturally and politically autonomous from the northern France-based central royal government. The region was under the influence of the people from the count territories of Toulouse, Provence, and ancient County of Barcelona. It was part of the wider cultural and linguistic region comprising the southern third of France known as Occitania. This area was finally brought under effective control of the French kings in the early 13th century as a result of the Albigensian Crusade, after which it was assigned governors. From the end of the thirteenth century Septimania evolved into the royal province of Languedoc.
The Kingdom of the Burgundians, or First Kingdom of Burgundy, was one of the so called "barbarian kingdoms" of the late Western Roman Empire in the fifth and sixth centuries. It began in what is now western Switzerland and southeastern France, and was ruled by Burgundian kings who were successors of the older House of Gibichung, but also held office as Roman military officers. In 451, the Burgundians helped the Roman-led allies defeat Attila at the Battle of the Catalaunian Plains, and in 455, they helped Roman-mandated forces led by Theodoric II, king of the Visigothic Kingdom, to defeat the Kingdom of the Suebi. After this, the Burgundians were able to expand their territories and their role in the Roman empire, and they moved their capital from Geneva to Lyon. In 534, the rule of the Burgundian kings ended and the kingdom became part of Francia.
The kingdom grew out of the 443 Imperial Roman resettlement of allied Burgundians to the region of Sapaudia, which at that time included Lake Geneva. These Burgundians were built around the remnants of a previous Roman-allied Burgundian kingdom which the Romans had allowed to settle on the western bank of their Rhine border at Borbetomagus, probably near Worms, having previously been Roman allies living east of the Rhine, outside the empire. The tribal ruler who was responsible for this move was Gundahar. In about 436, Gundahar and many of the people he led were killed by the Roman military leader Flavius Aetius working with his Hun allies.
Euric (Gothic: 𐌰𐌹𐍅𐌰𐍂𐌴𐌹𐌺𐍃, Aiwareiks, see Eric), also known as Evaric (c. 426 – 28 December 484), son of Theodoric I, ruled as king (rex) of the Visigoths, after murdering his brother, Theodoric II, from 466 until his death in 484. Sometimes he is called Euric II.
