In the early years after Vasco da Gama first landed near Calicut on the western coast of India on May 20, 1498, thePortuguese confined themselves to setting up a few feitorias (trading posts) on that coast. Before long, however, the imperial policy of King Manuel I (1495–1521) evolved into a plan to establish Portuguese power in Asia permanently by creating a chain of feitorias and fortresses in the Indian Ocean under a unified administration and to replace Venice with Lisbon as the chief port for the distribution of spices throughout Europe. This policy, which was often accompanied by violence, soon attracted the opposition of the Islamic powers in the region. The naval victory won at Diu in 1509 by Dom Francisco de Almeida, first viceroy and governor of Portuguese India (1505–1509), against an alliance of Islamic powers led by Mamluk Egypt and assisted by Venice marked a turning point. This triumph enabled Almeida's successor, Afonso de Albuquerque (1509–1515), to capture Goa (1510), Malacca (1511), and Ormuz (1515). He failed, however, to takeAden and so gain control of the Red Sea, to lay the foundations of the Estado da India, as the Portuguese maritimeempire in Asia later came to be called.
