Gundioc's son, Gundobad (r. 474-516), began commission for his kingdom's legal codification in 483, which his son and successor, Sigismund (r. 516-532) completed. The laws deal mostly with inheritance and monetary compensation for physical injury. The earlier work, "antiquae", and the later additions, "novellae", together make the whole Burgundian Code. The Franks began attacking the Burgundians in 523 and completely defeated them by 534, when Sigismund's brother, Godomar (r. 532-534), fled and left the kingdom to be divided amongst Frankish rulers. However, the Franks kept Burgundian law in practice.
