The Kingdom of Ormus (also known as Hormoz; Persian/Arabic: هرمز, Portuguese: "Ormuz") was located in the eastern side of the Persian Gulf and extending as far as Bahrain in the west at its zenith. The Kingdom was established by an Omani prince in the 11th century initially as a dependency of the Kerman Seljuk Sultanate, and later as an autonomous tributary of the Salghurids and the Ilkhanate of Iran. Ormus later became a client state of the Portuguese Empire, most of its territory was eventually annexed by the Safavid Empire in the 17th century.
