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".
