Life Inscription of Queen MargaretOn 17 September 1409, Margaret married King Martin of Catalonia-Aragon, a second cousin of her father. The bride was about fourteen years old and the groom fifty-three. King Martin I had survived all his legitimate children from his first marriage with Maria de Luna and was in need of a legitimate heir of his own. On 31 May 1410, Martin I died after six months of marriage. They had no children. His death led to a two-year interregnum, which was ended by the Pact of Caspe, in which Ferdinand I of Aragon, younger son of Martin's sister Eleanor, was chosen as the next king.

Margaret remained a widow for about four years. She married her second husband John of Vilaragut in 1415. In secret, she gave birth to a son in 1416, whose name was Joan Jeroni de Vilaragut (1416–1452). Her second husband John died in 1422 and Margaret entered the monastery of Bonrepòs in La Morera de Montsant. She died in 1429.
