Aymar II de Poitiers

Aymar II de Poitiers (c. 1180–1250) was count of Valentinois. Son of William I, he succeeded around 1189 and that year received the Diois in fief from Raymond V of Toulouse. Around 1195 he joined an Occitan poetic debate with troubadour Raimbaut de Vaqueiras.

He backed Toulouse in the Albigensian Crusade; in 1217 de Montfort's crusaders invaded the Valentinois and besieged Crest, which Aymar defended before making peace. He married Philippa de Fay, who brought wide Vivarais lands. His son William predeceased him, and his grandson Aymaret, the future Aymar III, ran the county from 1239.
