Eastern Arabia

Eastern Arabia (Arabic: ٱلْبَحْرَيْن, romanized: Al-Baḥrayn) is a region stretched from Basra to Khasab along the Persian Gulf coast and included parts of modern-day Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia (Eastern Province), and the United Arab Emirates. The entire coastal strip of Eastern Arabia was known as "Bahrain" for a millennium.

Until very recently, the whole of Eastern Arabia, from the Shatt al-Arab to the mountains of Oman, was a place where people moved around, settled and married unconcerned by national borders. The people of Eastern Arabia shared a culture based on the sea, as seafaring peoples.

Nowadays, Eastern Arabia is a part of the Arab states of the Persian Gulf. The modern-day states of Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates are the most commonly listed Gulf Arab states.

Most of Saudi Arabia is not geographically a part of Eastern Arabia.
