Карл II Лысый
Pepin died in 838 and his father Louis the Pious in 840. That same year, Pepin's son Pepin II was "elected" king by the nobles of Aquitaine (despite the fact Louis the Pious had granted the territory to his youngest son, Charles the Bald). So a dispute developed between Pepin II and King Charles the Bald. Bernard I of Septimania joined on the side of Pepin II. After he was captured at the Battle of Toulouse in 844, Charles the Bald ordered Septimania's execution in May 844.
