Aymar VI de Poitiers

Aymar VI de Poitiers, called the Fat (1322–1374 or 1376), was count of Valentinois and Diois, son of Louis I of Poitiers. He was lieutenant of the last independent dauphin of Viennois, then governed the Dauphiné for France from 1349 to 1355; the new dauphin, Charles, disliked the cession of Faucigny to Savoy and had him fined.

Seeking some independence between the Empire and the French crown, he won from Emperor Charles IV the honorary title of imperial vicar-general in the kingdom of Arles. In 1369 his town of Taulignan withstood a four-month siege.

He married Alix Roger de Beaufort, niece of Clement VI, and in 1372 her brother Gregory XI made him rector of the Comtat Venaissin, hoping the childless count's lands might pass to the Church. Aymar had so willed them in 1366, but in 1371 he named his cousin Louis II instead.
