Sheikdom of Upper Asir

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