Sigismund was King of the Burgundians from 516 until his death. He was the son of king Gundobad and Caretene. He succeeded his father in 516. Sigismund and his brother Godomar were defeated in battle by Clovis's sons, and Godomar fled. Sigismund was captured by Chlodomer, King of Orléans, where he was kept as a prisoner. Later he, his wife and his children were executed. Godomar then rallied the Burgundian army and won back his kingdom.
