Al-Ahsa (Arabic: الأحساء al-Aḥsāʾ, locally pronounced al-Ḥasāʾ) is the largest governorate in Saudi Arabia's Eastern Province, named after the Al-Ahsa oasis. The name Al-Ahsa is also given to the biggest city in the governorate, Hofuf. In classic Arabic, Ahsa means the sound of water underground. It has one of the largest oases in the world with Date Palms of the best in the world, the oasis is located about 60 km inland from the Persian Gulf. All urban areas are located in the traditional oasis of Al-Hasa. In addition to the oasis, the county also includes the giant Empty Quarter desert, making it the largest governorate in Saudi Arabia in terms of area. The Empty Quarter has the world's largest oil fields and connects Saudi Arabia to Qatar, the UAE, and Oman. The Governorate's population is over 908,366 (2005 estimate[update]). Though the population is mixed between Sunnis and Shi'ites, it contains one of the largest concentrations of Twelvers (اثنا عشرية) Shi'ite Muslims in the predominantly Sunni Muslim country. In the past, Al-Ahsa belonged to the historical region known as Bahrain, along with Qatif and the present-day Bahrain islands.
One campus of a major Saudi university, King Faisal University, founded in 1975, is located in Al-Ahsa with the faculties of agriculture, veterinary medicine and animal resources, with the other faculties in Dammam. The Hofuf campus also has facilities where Saudi women can study medicine, dentistry and home economics. A big branch of Arab Open University which is a private university is also located in Al-Ahsa.

Population and economy
According to 2005 estimate, Al-Ahsa has over 908,000 people. All are Muslims from both Sunnah and Shi'a Islam. Over the centuries, residents of the oasis have included the Banu Abdul Qays, the Banu Uqayl, and the Bani Khalid.
Oil production and agriculture are the two main economic activities of the Al-Ahsa. Al-Ahsa is the home of some of the richest oil fields in the world.
Natural fresh-water springs have surfaced in the region for millennia, encouraging human habitation and agricultural efforts (date palm cultivation especially) since prehistoric times. The Saudi Ministry of Agriculture established a factory to process its rich date harvest at the rate of five tons daily. Other components of its agricultural output include rice, corn, citrus, and other fruits. In addition, intensive livestock raising, involving thousands of sheep, goats, cattle and camels and more than 15 major poultry farms producing more than 100 million eggs a year, make Al-Ahsa one of the major food producers for the kingdom.
Manufacturing—both the traditional small-scale cottage industry kind (e.g. the traditional mislah mantle and pottery) and large-scale industries such as cement and plastics—has also been strongly encouraged

Al-Ahsa is a large area where a lot of villages and small towns are located. The villages are normally grouped into two main groups according to their relative location to the oasis. Although the villages lack big markets and/or hospitals, there are few good polyclinics and small markets. You can find small bank branches and automated teller machines in many villages. Recently[when?] there have been a great improvement in road maintenance and re-construction of some main roads between villages and cities. Al-Ahsa has about 50 villages, following is a list of some according to their location:

Al-Ahsa has a dry, tropical climate, with a five month summer and a relatively cold winter. It enjoys the benefit of copious reserves of underground water which has allowed the area to develop its agricultural potential. Nevertheless, Al-Ahsa has to deal with tons of sand which the wind carries and deposits over the land. To counter this problem, the Kingdom has planted large barriers of trees to prevent the wind-borne sand from damaging inhabited and agricultural areas.
