Chilperic II
The decline of the Kingdom began when they came under attack from their former Frank allies. In 523 the sons of Clovis I campaigned in the Burgundian lands, instigated by their mother Clotilde, whose father king Chilperic II of Burgundy had been killed by Gundobad. In 532 the Burgundians were decisively defeated by the Franks at Autun, whereafter king Godomar was killed and Burgundian lands was annexed by the Frankish Empire in 534.
