Martin I

Martin I was the king of Aragon from 1395 and of Sicily from 1409. He was the son of Peter IV and brother of John I of Aragon. Martin's reign was largely defined by Aragonese involvement in Sicily, which had a complex succession dispute following the death of Frederick III. Martin's son was to marry Frederick's heiress, Mary, and eventually, Martin became king of Aragon and ruled Sicily as Martin I. He died in 1409 without legitimate heirs, leading to further succession issues and the eventual union of the Aragonese and Sicilian crowns for nearly 300 years. Martin I of Sicily, also a skilled soldier, had to quell a revolt to maintain his rule on the island before his father succeeded him.12
