Sheikdom of Upper Asir

The Sheikdom of Upper Asir was an Arab state which was established in August 1916,^[1] after it broke away from the Idrisid Emirate of Asir,^[2] possibly with Hejazi aid.^[3] It was led by Hassan bin Ali Al Aidh.^[1] In 1920, Upper Asir faced Ikhwan revolts and Ibn Aidh's reign was threatened.^[3] In April to May 1920, Ibn Saud of the Emirate of Nejd intervened in support of the Ikhwan and defeated Ibn Aidh.^[3] Upper Asir was then partitioned between the Saudi and the Idrisi on 30 August 1920.^[3]
