Bahrain (historical Region)
Bahrain (Arabic: البحرين al-Baḥrayn) is a historical region in eastern Arabia that was known as the Province of Bahrain (Arabic: إقليم البحرين, Iqlīm al-Baḥrayn) until the 16th Century. It stretched from the south of Basra along the Persian Gulf coast and included the regions of Kuwait, Al-Hasa, Qatif, Qatar, and the Awal Islands, now known as Bahrain. The name "Bahrain" referred to the eastern mainland Arabia until the 18th century at least. The Arab inhabitants of the province were called Bahranis after that time.
