Pepin II of Aquitaine (823-865) is the eldest son of Pepin I (797-838) and the grand-son of Louis the Pious. He succeeded his father Pepin I, who died 13 December 838, by illegally seizing the throne and taking Toulouse in 843. Charles the Bald tried to dislodge but is obliged to recognize its sovereignty over Aquitaine in exchange for an oath of fealty. However, Pepin County loses Poitiers. The following years were not an uninterrupted series of wars and betrayals. Toulouse and Poitiers are plundered by the Normans. In 852, Pepin comes to Charles the Bald who does lock in Saint-Médard de Soissons. He escapes and revolts against his uncle again. The last ten years of his life, Pippin tries vainly to regain possession of his kingdom captive and died in 865 in Senlis.
