The Portuguese had had plans for establishing a fort at Calicut since 1500, when Pedro Álvares Cabral received this mission. The fort was finally completed in 1513, on the spot of an earlier "Serame", after a peace treaty was signed between the king of Portugal and the Zamorin. Hostilities were triggered when Duarte de Menezes attacked and destroyed a fleet of the Zamorin at Ponnani on 26 March 1525. Faced with the continuous hostility of the Zamorin however, the Portuguese decided to abandon and partly destroy the fort, which was then captured by the Zamorin.
