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.

Gundobad was King of the Burgundians (473–516), succeeding his father Gundioc of Burgundy. Previous to this, he had been a patrician of the moribund Western Roman Empire in 472–473, three years before its collapse, succeeding his uncle Ricimer. He is perhaps best known today as the probable issuer of the Lex Burgundionum legal codes, which synthesized Roman law with ancient Germanic customs. He was the husband of Caretene.
