クロタール2世
Brunhilda was apparently an efficient ruler, but this and her forceful personality brought her into conflict with her nobles, the church and the other Merovingians. Her bitter feud with Fredegund, mistress of Chilperic I of Neustria, who murdered Brunhilda's sister, Queen Galswintha, c. 568 in order to replace her as queen, lasted until Fredegund's death in 597. Fredegund had Brunhilda's husband murdered and Brunhilda imprisoned for a period. This feud was continued by Fredegund's son, Chlothar II, who in 613 defeated Brunhilda in battle and had her executed by being pulled apart by four horses.
