▪ king of Portugal

Portuguese  Sebastião  

born Jan. 20, 1554, Lisbon, Port.

died Aug. 4, 1578, near Alcazarquivir, Mor.

      king of Portugal from 1557, a fanatically religious ruler who lost his life in a crusade against the Muslims in Morocco. After his death, many of his subjects believed that he would return to deliver them from Spanish rule, a messianic faith known as Sebastianism (Sebastianismo).

      Sebastian was the posthumous son of John, heir to the Portuguese throne, and succeeded his grandfather, John III, at the age of three. He was austerely educated by Jesuits and, as he grew into manhood, saw himself as Christ's captain, destined to win victories over the Muslims. Neither his grandmother, Queen Catherine, nor his great-uncle, Cardinal Henry, had much influence over him. He took power in 1568 and devoted himself to his overriding ambition, reversing the policy of John III, which had been to withdraw from costly conquests. In 1578 Sebastian led a large force of Portuguese and international adventurers that landed near Larache and was crushed by a greatly superior Moroccan army. The myth that he survived the battle gave rise to the mystical Sebastianism. Four impostors claimed to be Sebastian between 1584 and 1598.
