The Lex Burgundionum is a legal code that was established by the Burgundians, a Germanic tribe, in the 5th century. It served as a set of laws governing the social and legal matters of the Burgundian people, reflecting their customs and traditions. The code is significant for its insights into early medieval law and society. This legal document is one of the earliest examples of written law in the region that is now part of modern-day France. It is often studied alongside other legal codes, such as the Lex Salica, which was used by the Franks, to understand the development of law in post-Roman Europe.
