Martin I of Sicily (1374–1409)
Born 1374 CE, died 1409 CE.
Martin I of Sicily (c. 1374/1376 – 25 July 1409), called the Younger, was King of Sicily from his marriage to Queen Maria in 1390 until his death in 1409. Martin's father was the future King Martin I of Aragon, and his grandparents were King Peter IV of Aragon and Eleanor of Sicily. In February 1390 he married Maria of Sicily, born in 1362/1363. In 1392 he returned with Maria to Sicily with a military force and defeated a group of opposing barons. In 1398 the couple had their only son Peter, crown prince of Sicily, who died in 1400. He ruled Sicily jointly with Maria until her death at Lentini on 25 May 1401. At that time, he repudiated the Treaty of Villeneuve (1372) and ruled Sicily alone. After his death in 1409 in Cagliari, Sardinia, his father, by then king of Aragon, ruled Sicily as Martin II. After Maria's death Martin I the Younger married at Catania on 21 May 1402 by proxy and on 26 December 1402 in person Blanche of Navarre, who was heiress of the Evreux family and the future queen of Navarre, by whom he had an only son Martin in 1403, who died in Valencia in 1407.
