Al-Ahsa, historically known as Hajar and also referred to as Al-Hasa, is a governorate in the Eastern Province of Saudi Arabia. It is the largest governorate in the country by area, covering approximately 375,000 km². As of 2022, it had a population of 1,104,267. Its seat is Hofuf.

History

The habitation of the oasis of Al-Ahsa goes back into the pre-history of human existence, which was started by the pastoral Semites, and the subsequent migrations of the major Semitic tribes in the Arabian Peninsula to the north and east. Additionally, it has served as a commercial crossroads of trade routes linking the Arabian Peninsula with Persia and India through the port of Uqair and the port of Qatif. In terms of agricultural importance, Al-Ahsa is of great importance since its area is made up of fertile lands and contains abundant water sources.

The Jerhaites, a branch of the Chaldeans, settled in the region. The description of their city came from the Greek traveler Strabo, who said about Al-Ahsa: <blockquote>"It was founded by Chaldean immigrants from Babylon in a swampy land, and it was built of salt stones, eighty thousand cubits away from the sword of the sea."</blockquote>The Greek historian Polybius also described Al-Ahsa as an important commercial center, one of the active markets in the Arab countries, and a crossroads for the caravan routes coming from southern Arabia, the Levant, the Hijaz, Iraq and India.

City of Hejir

Al-Ahsa then became a part of a city belonging to the territory of Bahrain at that time, located between Ras Al-Qara mountain, Abu Hasis mountain, and the northern part of Jabal al-Qarah in Al-Ahsa today a place now called the town of Al-Kawarij. The town was of importance to the inhabitants of the Arabian Peninsula, because of the port of Al-Uqair, which served as a link in bringing goods and exporting them to and from Persia, India, China, Africa and Mesopotamia.The port made it the great market for the central and eastern regions of it.

When the Islamic call appeared, the Messenger Muhammad sent Al-Ala bin Abdullah Al-Hadrami in the seventh century AD corresponding to the eighth year of the Hijri to invite the people of Hejir to Islam, which they accepted.

Islamic times

Eastern Arabia was conquered by the emerging Rashidun Caliphate during the 7th century. It was later inherited by the Umayyads and Abbasids. In 899 A.D., the region came under the control of the Qarmatian leader, Abu Tahir al-Jannabi, and was declared independent from the Abbasid Caliphate of Baghdad. Its capital was at al-Mu'miniya near modern Hofuf. By circa 1000, Al-Hasa became the 9th largest city worldwide, supporting 100,000 inhabitants. In 1077, the Qarmatian state of Al-Ahsa was overthrown by the Uyunids. Al-Ahsa subsequently fell under the rule of the Bahrani dynasty of the Usfurids, followed by their relatives, the Jabrids, who became one of the most formidable powers in the region, retaking the islands of Bahrain from the princes of Hormuz. The last Jabrid ruler of Bahrain was Muqrin ibn Zamil.

In 1521, the Portuguese Empire conquered the Awal Islands (the islands that comprise present day Bahrain) from the Jabrid ruler Muqrin ibn Zamil, who fell strongly in battle. The Jabrids struggled to maintain their position on the mainland in the face of the Ottomans and their tribal allies, the Muntafiq. In 1550, Al-Ahsa and nearby Qatif came under the sovereignty of the Ottoman Empire with Sultan Suleiman I and was later lost to the Portuguese in 1551.

The Ottomans were expelled from Al-Ahsa in 1670, and the region came under the rule of the chiefs of Banu Khalid tribe.

Al-Ahsa, along with Qatif, was incorporated into the Wahhabist Emirate of Diriyah in 1795, but returned to Ottoman control in 1818 with an invasion ordered by Muhammad Ali of Egypt. The Banu Khalid were again installed as rulers of the region but, in 1830, the Emirate of Nejd retook the region.

Direct Ottoman rule was restored in 1871, and Al-Ahsa was placed first under Baghdad Vilayet and with Baghdad's subdivision Basra Vilayet in 1875. In 1913, ibn Saud, the founder of modern Saudi Arabia, annexed Al-Ahsa and Qatif into his domain of Najd.
