Martin I of Sicily (c. 1374 — 25 July 1409), "The Younger", King of Sicily (1390 - 1409), was the grandson of Peter IV of Aragon and Leonora of Sicily, and nephew of John I of Aragon. In 1390 he married Mary of Sicily. In 1392 he returned with Mary to Sicily with a military force and defeated a group of opposing barons. He ruled Sicily jointly with Mary until her death in 1402. At the time, he repudiated the Treaty of 1372 and ruled Sicily alone. After his death in 1409 in Cagliari, Sardinia, his father, Martin I of Aragon, ruled Sicily as Martin II. Martin the Younger married secondly Blanche of Navarre, who was heiress of the Evreux family and the future queen of Navarre. Any offpring of his two marriages did not survive childhood, thus the only issue he left was a bastard son, Fadrique de Luna, whom the grandfather tried to make the successor in the Aragonese Empire. But he did not obtain sufficient support and, when he presented his claim, was denied by the Pact of Caspe. Martin the Younger led the troops in the conquest of Sardinia in 1409, decisively defeating the ruler of Arborea at Sanluri just before his own death.
