King of Portugal (1385–1433), the illegitimate son of Pedro I. He led nationalist sympathizers against the Castilians, who supported Queen Eleanor, his rival. Defeating their invasion he went on to ally with England (through his marriage to Philippa, daughter of John of Gaunt) and to encourage African and Western exploration. His reign was the start of Portugal's period of colonial and maritime expansion; his sons, including Henry the Navigator, consolidated his achievements.
