History
The Gulf coast was part of the ancient world of Dilmun, the trading culture centred on Bahrain, and Tarout island, off Qatif, has been settled for some five thousand years. The great oasis of al-Hasa, now Al-Ahsa, fed towns and caravan routes long before Islam, and its Abd al-Qays tribe was among the first to accept the new faith; the Jawatha mosque near Hofuf is traditionally one of the earliest in Arabia. In the 10th century Al-Ahsa was the base of the Qarmatians, a radical Ismaili movement that raided Mecca in 930 and carried off the Black Stone of the Kaaba for about twenty years.
Later the region was ruled by local dynasties, briefly by the Portuguese at the coast, and by the Ottomans, who held al-Hasa in the 16th and 17th centuries and again from 1871. The Bani Khalid tribe controlled the area in between. Ibn Saud took Hofuf from the Ottomans in 1913, and at Uqair in 1922 British officials drew the borders with Kuwait and Iraq.
In 1938 American geologists struck oil at Dammam Well No. 7 in Dhahran, and the company that became Saudi Aramco built a new world around it: Dhahran's company town, the ports of Ras Tanura and Dammam, and later the industrial city of Jubail. The province's Shia communities have long complained of discrimination, and Qatif saw protests in 2011–12 and the demolition of the old quarter of Awamiyah in 2017.
