Карл II Лысый
In 845, following these events, Charles the Bald signed a treaty recognizing Pippin II as king of Aquitaine in exchange for him relinquishing the northern part of Aquitaine (the county of Poitiers) to Charles the Bald. However, the Aquitanians grew very unhappy with their king Pippin II, perhaps for his friendliness towards the Vikings who inflicted terrible damage on the population, and so in 848 they called Charles the Bald to topple Pippin II. In 849 Charles the Bald moved south again and was presented the capital of Aquitaine, Toulouse, by Frédelon, the count of Toulouse recently appointed by Pippin II. Charles the Bald then officially confirmed Frédelon as count of Toulouse. Soon the whole of Aquitaine was submitting to Charles the Bald. In 852, Pippin II was taken prisoner by the Basques and handed over to his uncle Charles the Bald who put him in a monastery.
