 The "Liber" is one of the primary sources for contemporary Burgundian life, as well as the history of its kings.Like many of the Germanic tribes, the Burgundians' legal traditions allowed the application of separate laws for separate ethnicities.Thus, in addition to the "Lex Gundobada", Gundobad also issued (or codified) a set of laws for Roman subjects of the Burgundian kingdom, the "Lex Romana Burgundionum" ("The Roman Law of the Burgundians").
