Chlothar I
Gundoald or Gundovald was a Merovingian usurper king in the area of southern Gaul in either 584 or 585. He claimed to be an illegitimate son of Chlothar I and, with the financial support of the Emperor Maurice, took some major cities in southern Gaul, such as Poitiers and Toulouse, which belonged to Guntram, king of Burgundy, a legitimate son of Chlothar I. Guntram marched against him, calling him nothing more than a miller's son and named him 'Ballomer'. Gundovald fled to Comminges and Guntram's army set down to besiege the citadel (now known as Saint-Bertrand-de-Comminges). The siege was successful, Gundovald's support drained away quickly and he was handed over by the besieged to be executed.
