Hugh XI of Lusignan

Hugh XI of Lusignan (c. 1221–1250), called the Brown, was the eldest son of Hugh X of Lusignan and Isabelle of Angoulême. Betrothed in 1224 and 1227, he married neither; in 1236 he married Yolande, daughter of Peter I of Brittany.

He inherited Angoulême from his mother in 1246 and La Marche from his father in 1249. That year he agreed to serve the count of Poitiers for a year on the crusade.

He joined Louis IX on the Seventh Crusade and was killed on 6 April 1250 at the Battle of Fariskur in Egypt. His son Hugh XII succeeded him.
