The Lex Burgundionum (Burgundian Laws, also lex gundobada or loi gombette) refers to the law code of the Burgundians, probably issued by king Gundobad. It is influenced by Roman law and deals with domestic laws concerning marriage and inheritance as well as regulating weregild and other penalties. Interaction between Burgundians is treated separately from interaction between Burgundians and Gallo-Romans. The oldest of the 14 surviving manuscripts of the text dates to the 9th century, but the code's institution is ascribed to king Gundobad (died 516), with a possible revision by his successor Sigismund (died 523). The Lex Romana Burgundionum is a separate code, containing various laws taken from Roman sources, probably intended to apply to the Burgundians' Gallo-Roman subjects. The oldest copy of this text dates to the 7th century.
The Lex Burgundionum code was compiled by King Gundobad (474-516), very probably after his defeat by Clovis I in 500. Some additamenta were subsequently introduced, either by Gundobad himself or by his son Sigismund. This law bears the title of Liber Constitutionum, indicating that it emanated from the king; it is also known as the Lex Gundobada or Lex Gombata. It was used for cases between Burgundians, and was also applicable to cases between Burgundians and Romans. For cases between Romans, however, Gundobad compiled the Lex Romana Burgundionum, called sometimes, through a misreading of the manuscript, the Liber Papiani, or simply Papianus.
The Burgundian kingdom is one of the early Germanic kingdoms that existed within the Roman Empire. In the late fifth and early sixth centuries, the Burgundian kings Gundobad and Sigismund compiled and codified laws to govern the members of their Barbarian tribe, as well as Romans living amongst them. Those laws governing the Burgundians themselves are called collectively the Lex Burgundionum, while the laws governing the Romans are known collectively as the Lex Romana Burgundionum. Both are extant. The laws codified in the Burgundian Code reflect the earliest fusion of German tribal culture with the Roman system of government. It promoted and helped maintain harmonious relations between such widely different people who had been previous enemies. More devotion has been given to other Germanic tribes of this time and little is known about the culture and way of life of the Burgundians beyond what can be inferred from their legal code. Dr. Katherine Fischer Drew claims that it is the most influential of all barbarian law codes because of its survival, even after Frankish conquest, until the ninth century.
