Guy II of Thouars

Guy II of Thouars (1246/1249–1308), son of Aimery IX and Marguerite of Lusignan, joined his uncle Savary IV and other Poitevin barons in a 1269 agreement with Alphonse of Poitiers. Around 1274 he succeeded Savary as viscount of Thouars under Poitou's viage custom, by which fiefs passed first through the late lord's brothers; the custom was abolished soon afterward.

He then faced claims from kinswomen over pensions and lands, and the Parlement of Paris ordered him to pay his aunt Eleanor of Soissons an annuity in return for her landed rights.

In 1304 Philip IV summoned him for the Flanders war. He died on 21 September 1308, leaving the viscounty to his son Jean I.
