In September 1922, the Council of the League of Nations recognized Transjordan as a state under the terms of the Transjordan memorandum. Transjordan remained a British mandate until 1946, but it had been granted a greater level of autonomy than the region west of the Jordan River. Multiple difficulties emerged upon the assumption of power in the region by the Hashemite leadership. In Transjordan, small local rebellions at Kura in 1921 and 1923 were suppressed by the Emir's forces with the help of the British. Wahhabis from Najd regained strength and repeatedly raided the southern parts of his territory in (1922–1924), seriously threatening the Emir's position. The Emir was unable to repel those raids without the aid of the local Bedouin tribes and the British, who maintained a military base with a small RAF detachment close to Amman.
