Hussein bin Ali, Sharif of Mecca
Within Turkey, a progressive, secular nationalist movement arose, known as the Turkish national movement. During the Turkish War of Independence (1919–1923), the Turkish revolutionaries, led by Mustafa Kemal Atatürk, abolished the Treaty of Sèvres with the Treaty of Lausanne (1923). Pursuant to Atatürk's Reforms, the Republic of Turkey abolished the position of caliphate in 1924. Atatürk offered the caliphate to Ahmed Sharif as-Senussi, on the condition that he reside outside Turkey; Senussi declined the offer and confirmed his support for Abdulmejid. The title was then claimed by Hussein bin Ali, Sharif of Mecca and Hejaz, leader of the Arab Revolt, but his kingdom was defeated and annexed by ibn Saud in 1925.
