Hugh IX "le Brun" of Lusignan (1163/1168 – 5 November 1219)[1] was the grandson of Hugh VIII. His father, also Hugh (b. c. 1141), was the co-seigneur of Lusignan from 1164, marrying a woman named Orengarde before 1162 or about 1167 and dying in 1169. Hugh IX became seigneur of Lusignan in 1172, seigneur of Couhé and Chateau-Larcher in the 1190s, and Count of La Marche (as Hugh IV) on his grandfather's death. (c. 1165–1171) Hugh IX died on the Fifth Crusade at the siege of Damietta on 5 November 1219.[1]
Hugh IX is mentioned under the pseudonym Maracdes ("Emerald") in two poems by the troubadour Gaucelm Faidit, according to the Occitan razós to these poems.
