Martin was born in 1356, in either
Girona or
Perpignan, both then in the
Principality of Catalonia. He was the second son of King
Peter IV of Aragon and
Eleanor of Sicily (Leonora), princess of the Sicilian
branch of the
House of Aragon. As a cadet prince of the Aragonese royal family, Martin was given the County of
Besalú. In
Barcelona on 13 June 1372, Martin married
María López de Luna (d.
Villarreal, 20 December 1406), the daughter and heiress of Lope, Lord and 1st Count of
Luna and Lord of
Segorbe and his wife Brianda de Got, who was born in
Provence and was related to
Pope Clement V. In 1380, his father appointed him lord and
regent of the island of Sicily, then known also as
Trinacria, since its queen
Maria of Sicily, who was also Martin's cousin, was underage (Maria's father,
Frederick III the Simple, died in 1377). As a son of Eleanor of Sicily, Martin was himself an heir to the island, should Maria's family die out. Martin's only living son,
Martin the Younger, about seventeen years old, was married in 1391 to the Queen of Sicily. After the marriage, Martin the Younger left Aragon and, having arrived in
Palermo, was crowned, together with Maria, becoming King Martin I of Sicily. The
Sicilians did not like the Aragonese marriage too much (also because it had been celebrated by the
Antipope Clement VII and the Sicilians were supporters of
Pope Urban VI and then of
Pope Boniface IX) and, led by the Alagona family, rebelled already in 1392 and from that date opposed the Aragonese authority. In the same 1392, Martin the Elder was sent to Sicily at the head of an expedition (which had been organized to intervene in
Sardinia, but during the trip it was diverted to Sicily) to help his son, Martin the Younger and Queen Maria. The arrival of Martin the Elder in Sicily led to the conquest of
Trapani and Palermo, but he was unable to defeat the opponents, who resisted until 1398, the year in which peace returned and the son and daughter-in-law were able to govern the whole island again. ==Kingship==
