The siege of Diu occurred when a combined Ottoman-Gujarati force defeated a Portuguese attempt to capture the city of Diu in 1531. The victory was partly the result of Ottoman firepower over the Portuguese besiegers deployed by Mustafa Bayram, an Ottoman expert.[14]

Shortly before the siege they encountered roughly 800 enemy soldiers at Siyâl Bet island[a], engaged them in combat, and killed them all.[15] There were 9[16] or 17 Portuguese killed and 120 wounded.[17] They then sailed for Diu, but the Muslim alliance defeated them and killed 14.[18]

Although Diu was successfully defended, victory was short-lived: Diu was blockaded and the Portuguese armada was diverted towards more exposed Gujarati cities.[19] Ghogha, Surat, Mangrol, Somnath, Bassein, Tarapur, Kelva, Mahim, Bulsar, Agashi, Patam, Pate, and many smaller settlements were assaulted and sacked, some never recovering from the attacks.[20][21][12]

In 1534, Sultan Bahadur of Gujarat signed a peace treaty with Governor Nuno da Cunha, granting the Portuguese the territory of Bassein, including Bombay. In 1535, the Portuguese were allowed to construct a fortress at Diu.
