After his death in 1409 in Cagliari, Sardinia, his father, by then king of Aragon, ruled Sicily as Martin II.

No offspring of his two marriages survived childhood; the only issue he left was a bastard son by Sicilian-born Tarsia Rizzari, Fadrique of Aragon, Count of Luna and Ejerica and Lord of Segorbe, born in 1400/1403, whom Martin II tried to make his successor in the Aragonese Empire.

Fadrique married Yolande Louise (Violante Luisa) de Mur and died at Urena in 1438 without issue.

He also left a bastard daughter by Sicilian-born Agathe de Pesce, named Violante of Aragon, who died c. 1428.

Martin the Younger led the troops in the conquest of Sardinia in 1409, decisively defeating the ruler of Arborea at the Battle of Sanluri just before his own death.
