Guy I of Lusignan
Guy I of Lusignan (1269–1308), also called Guiard, was the younger son of Hugh XII of Lusignan. His brother Hugh XIII disinherited him in 1297, but after Hugh's death in 1303 Guy claimed La Marche and Angoulême; King Philip IV backed him and the Parlement of Paris confirmed them in 1304.
He fought for the king at Mons-en-Pévèle the same year, but in 1305 he made terms with the English at Saintes, ceding Cognac and Merpins for the seneschalship of Saintonge.
Accused before Philip in 1308 for homage to the English king, he died childless that November before trial, ending the senior male line of Lusignan.
