Jean de Béthencourt was, after his death, succeeded by his nephew Maciot de Béthencourt, who turned out to be a tyrant. He established Teguise as the new capital. The Portuguese had been competing with the Castilians for the islands. The Castilians suspected that Maciot would sell the islands to them, which he did in 1448. Neither the natives nor the Castilians approved, and this led to a revolt which lasted until 1459 when the Portuguese were forced to leave. Portugal formally recognised Castile as the ruler of the Canary Islands in 1479 as part of the Treaty of Alcáçovas.
