Sigismund of Burgundy
Sigismund (died 524) was king of the Burgundians from 516 to his death. He was the son of king Gundobad, whom he succeeded in 516. Sigismund and his brother Godomar were defeated in battle by Clovis' sons and Godomar fled. Sigismund was taken by Chlodomer, King of Orléans, where he was kept as a prisoner. Later he, his wife and children were executed. Godomar then rallied the Burgundian army and won back his kingdom. Meanwhile, Chlodomer ordered the death of Sigismund and marched with his brother Theuderic I, King of Metz, on Burgundy in 524.
Life
Sigismund was a student of Avitus of Vienne, the Catholic bishop of Vienne who converted Sigismund from the Arian faith of his Burgundian forebears. Sigismund was inspired to found a monastery dedicated to Saint Maurice at Agaune in Valais in 515. The following year he became king of the Burgundians. Sigismund's son opposed him in 517, and insulted his new wife, so Sigismund had him strangled. Then, overcome with remorse, Sigismund retreated to the monastery that he had founded.
