Editing Chlothar I (section)

===First Burgundian War===
In 516, [[Gundobad]], king of Burgundy, died, and the throne passed to his son [[Sigismund of Burgundy|Sigismund]], who converted to Catholicism. Sigismund adopted an extreme anti-Arian policy, going so far as to execute his Arian son Sigeric, who was the grandson of the Ostrogoth King [[Theoderic the Great]]. Sigismund also nearly prompted the Franks to launch an offensive against him, but he avoided a conflict by giving one of his daughters, [[Suavegotha]], in marriage to Chlothar's older half-brother, [[Theuderic I]].

In 523, at the instigation of their mother, Clotilde, Chlothar, Childebert, and Chlodomer joined forces in an expedition against the Burgundians. The Burgundian army was defeated, and Sigismund was captured and executed. Sigismund's brother [[Godomar]] replaced him on the throne, with the support of the aristocracy, and the Franks were forced to leave.

In 524, Chlothar, his brothers and Theuderic, began a new campaign, advancing to the Isère Valley. But on 25 June 524, they suffered a serious defeat at the [[Battle of Vézeronce]], and Chlodomer was killed. The Franks left Burgundy, and Godomar resumed his rule until 534.<ref>Récit des campagnes burgondes : Lebecq, p. 65.</ref>
