As vassals of the Portuguese state, the Kingdom of Ormus jointly participated in the 1521 invasion of Bahrain that ended Jabrid rule of the Persian Gulf archipelago. The Jabrid ruler was nominally a vassal of Ormus, but the Jabrid King, Muqrin ibn Zamil had refused to pay the tribute Ormus demanded, prompting the invasion under the command of the Portuguese conqueror, António Correia. In the fighting for Bahrain, most of the combat was carried out by Portuguese troops, while the Ormusi admiral, Reis Xarafo, looked on. The Portuguese ruled Bahrain through a series of Ormusi governors. However, the Sunni Ormusi were not popular with Bahrain's Shia population which suffered religious disadvantages, prompting rebellion. In one case, the Ormusi governor was crucified by rebels, and Portuguese rule came to an end in 1602 after the Ormusi governor, who was a relative of the Ormusi king, started executing members of Bahrain's leading families.
