Hugh IX of Lusignan

Hugh IX, called le Brun or the Brown (before 1151–1219), was a Poitevin lord of Lusignan who followed Richard the Lionheart on the Third Crusade. He followed Richard to Sicily in 1190 and to the siege of Acre the next year.

In December 1199 he detained Eleanor of Aquitaine and in return secured the county of La Marche. When King John married Isabella of Angoulême, his appeal to Philip Augustus helped bring the 1202 sentence against John's French fiefs.

Reconciled in 1214, he fought beside John at La Roche-aux-Moines. He joined the Fifth Crusade and died at the siege of Damietta on 11 August 1219.
