Al-Ain is the main settlement[7][8] in the Eastern Region of the Emirate of Abu Dhabi, located on the country's eastern border with Oman, where the adjacent town of Al-Buraimi is located. The region is located to the west of the Western Hajar Mountains[9] and the Gulf of Oman,[1] and in the vicinity of the Rub' al-Khali Desert.[3] On the coast of the Arabian or Persian Gulf lies Jumayra in the Emirate of Dubai, which was probably part of this region.[5][10]
The word 'Tawam' means 'twins', and it reportedly refers to a pair of alfaj (water channels) in the Buraimi region, as identified from the works of people like Salil ibn Raziq in the 19th century, Al-Tabari and Al-Muqaddasi[3] in the 10th century, and consequently people in the 21st century like Timothy Power, an archaeologist and assistant-professor based in Abu Dhabi who helped to found the Buraimi Oasis Landscape Archaeology Project. That said, the region is composed of oases which depended on alfaj for irrigation,[9] such as those of Al-Ain and Qattarah in Al-Ain, and Hamasa in Al-Buraimi.[5]
In the mid-19th century, an Omani scholar, Salil ibn Raziq, basically said that Buraimi used to be called Tawam. People picked up on that but have never critically examined the earlier sources.
Al Tabari writes of a Persian sphere of influence along the Batinah plain of Oman and an Arab sphere of influence in the interior with its capital at a place called Tawam. In that he deals with the events of 893/94, in which there is a dispute amongst different local factions about who should rule in Oman. One of these factions approaches the Abbasids for outside assistance. The faction who do this are called the Bani Sama and they are based in Buraimi before they base themselves in Sohar, call themselves the Wajihid Dynasty and assume the leadership of the whole region.
Hafit {Tuwwam} abounds in palm trees; it lies in the direction of Hajar {Al Hasa}, and the mosque is in the markets ... Dibba and Julfar, both in the direction of the Hajar, are close to the sea ... Tuwwam has been dominated by a branch of the Quraysh ...
Archaeological remains dating to the Bronze Age and beyond, like at Al-Rumailah, Hili and Jebel Hafeet,[11][12] have been found in this region. In ancient times, the region was reportedly used by Arabs as a place of gathering,[4][5] and like Dibba, it was taxed by Al-Julanda, who were clients of the Sasanians, who reported to the Persianmarzban (military governor), who was based at Al-Rustaq in what is now Oman.[10]
Around the Islamic Golden Age in the Middle Ages, the region, with its capital at 'Tawam', was an important sphere of influence for Arabs. Ceramics and other materials found here were believed to have been imported from Mesopotamia, India and China. At this time, Sohar, located to the east of this region, was of such prominence as a trading port on the coast of the Gulf of Oman that it was considered[by whom?] to be the "Dubai or Singapore of its day"[citation needed]. A mosque, considered[how?] to be the oldest in the country, was found[when?] in the vicinity of the Sheikh Khalifa Mosque in Al-Ain by Dr Walid Al Tikriti, besides a falaj, a group of houses, and a village dating to the 9th or 10th century.[5][citation needed]
Being strategically located near the Western Hajar, the area was[when?] an important stop for people and caravans traveling between the mountains and other parts of Arabia, such as Al-Hasa. Not only was the area, being rich in date palms, important for trade, but it was also used by certain people for smuggling slaves, women or children, years before the foundation of the UAE.[9]
