In 1869, the Qubaisat tribe settled at Khawr al Udayd and tried to enlist the support of the Ottomans, whose flag was occasionally seen flying there. Khawr al Udayd was claimed by Abu Dhabi at that time, a claim supported by the British. In 1906, the British Political Resident, Percy Cox, confirmed in writing to the ruler of Abu Dhabi, Zayed bin Khalifa Al Nahyan ('Zayed the Great') that Khawr al Udayd belonged to his sheikhdom.
