“Bahrain” once meant two seas along the whole Gulf shore
Eastern Arabia—historically Al-Baḥrayn—names the Gulf coast from Basra toward Khasab, overlapping parts of today’s Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE. Until recent borders, people moved, married, and traded as seafarers across that littoral.
Today the region lies within the seven Gulf Arab states, although most of Iraq and Saudi Arabia fall outside it; the Iraqi share is Basra Governorate and the Saudi share the Eastern Province. For about a thousand years the whole coastal strip went by the name Bahrain.
Al-Baḥrayn is the dual of the Arabic baḥr, sea, so it means the two seas, though nobody agrees which two. In its five Qur'anic appearances it points not to the island, which Arabs called Awal, but to two mainland oases, al-Qatif and Hajar, the latter now called Al-Aḥsā. It probably came to mean only the archipelago after the fifteenth century. Modern explanations include the bays on either side of the coast, the waters north and south of the island, or salt water above and fresh water below, since freshwater springs bubble up in the sea north of Bahrain, as visitors have noted since antiquity. Older theories paired the ocean with a calm inland lake, or suggested that a simpler adjective form was avoided because it would have been misread.
Geographically, Khaleeji or Gulf Arab means someone from this coast, but the word has become a broader identity for GCC citizens, distinct from the wider Arab world. Coastal communities share music such as fijiri, sawt and liwa and a life oriented to the sea, with livelihoods traditionally drawn from marine trades. They speak Gulf Arabic, including about 2 million of Saudi Arabia's 34 million people.
Gulf entertainment travels widely: its influence reaches Tunisia, and Kuwaiti poetry, film, theatre and soap operas are exported to neighbours. Al Jazeera, Al Arabiya and MBC, the Arab world's three largest broadcasters, are all based here. Islam dominates, split among Sunni, Shia and the Ibadi school that prevails in Oman.
