By the turn of the 20th century, the Naqbiyin had mostly settled in the emirate of Sharjah and were to be found in Khor Fakkan, Kalba as well as Dibba and Fahlain (today a suburb of Ras Al Khaimah).
[4] Khatt and Fahlain, two villages on the Jiri plain where the Naqbiyin dominate the population, formed part of the Sheikhdom of the 19th century Qawasim ruler of Ras Al Khaimah, Hassan bin Rahma, who signed the General Maritime Treaty of 1820 with the British.
Khatt was populated in the main by members of the 'Awanat, Sharqiyin, and Naqbiyin tribes[6] – today the Al Naqbi Tower still stands in the village.
[10] Considered to have been present in Khor Fakkan prior to the Portuguese sack of that town under Albuquerque in 1506, the Naqbiyin were settled in strategic locations, given lands by the Al Qasimi, as a protection against the Sharqiyin.
[11] The almost constant outbreaks of squabbling and disputes between Kalba and neighbouring Fujairah (itself only recognised as a Trucial State by the British in 1952) broke out into open fighting over a land dispute after the UAE was founded in 1971 and, in 1972 the newly founded Union Defence Force was called in to take control of the fighting which, by the time the UDF moved in, had killed 22 and seriously injured a dozen more.
