Boso II of Périgord

Boso II, third son of Boso the Old, succeeded his brother Adalbert I as count of La Marche and Périgord in 997, despite the claims of Adalbert's young son Bernard. In 1000 he fought for his suzerain William V of Aquitaine against Adémar of Limoges.

The chronicler Adémar de Chabannes accused Boso's unnamed wife of poisoning him after his return from Rome. By William V's award of 1008, Périgord passed to Boso's son Hélie and La Marche to his nephew Bernard I.
