Bahrain Island has only ever been referred to as Bahrain Island.
Until the late Middle Ages, "Bahrain" referred to the region of Eastern Arabia that included Southern Iraq, Kuwait, Al-Hasa, Qatif, and Bahrain
 Following a period of Arab rule, Bahrain was ruled by the Portuguese Empire from 1521 until 1602, when they were expelled by Shah Abbas I of the Safavid dynasty
