Aymar V de Poitiers

Aymar V de Poitiers (c. 1271–1339/40), count of Valentinois and Diois, was the eldest son of Aymar IV and Hippolyte of Burgundy. He succeeded in 1329 at about sixty, and a later historian judged him weak and fond of pleasure.

He did not carry on the old fight with the bishop of Valence: he made peace at Avignon in 1332, ending his family's long quarrel with the Church. His last years went on the Clérieu inheritance, which his brother and Humbert II, dauphin of Viennois, also claimed.

Arbitration favored Aymar in 1336, but the dauphin would not accept it, and after a suit reaching the pope, Aymar did liege homage to him at Chabeuil in 1338. His will of 1339 named his son Louis heir; he died soon after at Baix, in 1339 or 1340.
