In 1505 the reign King Manuel I of Portugal led Portugal to establish a policy of expansion in Africa and western Asia. During attempts to expand Portuguese influence into the Indian Ocean, the Portuguese duke Afonso de Albuquerque captured the island in 1507 and it was incorporated into the greater Portuguese Empire. The Portuguese constructed a fortress on the island to deter potential invaders, naming it the Fort of Our Lady of the Conception. The island became an emergency stopover point for Portuguese ships travelling to Goa, Gujarat and nearby Kishm. The Ottomans laid siege to the island under the admiral and cartographer Piri Reis in 1552. In 1622 the island was captured from the Portuguese by a combined Anglo-Persian force at the behest of the English East India Company.
