Hugh X of Lusignan

Hugh X of Lusignan (c. 1182–1249) succeeded his father Hugh IX as count of La Marche in 1219. In 1220 he married Isabella of Angoulême, widow of John of England, becoming count of Angoulême.

He used the conflict between Capetians and Plantagenets to strengthen his authority in Aquitaine. He wavered between the two courts until 1241, when he defied Louis IX and Alphonse of Poitiers and raised Poitou in revolt. The rising collapsed with the royal victory at Taillebourg in 1242.

In 1248 he joined Louis IX's Seventh Crusade. He was killed outside Damietta on 5 June 1249, where his father had died in 1219.
