The Khilafat movement, also known as the Indian Muslim movement (1919–24), was a pan-Islamist political protest campaign launched by Muslims of British India led by Shaukat Ali, Maulana Mohammad Ali Jauhar, Hakim Ajmal Khan, and Abul Kalam Azad to restore the caliph of the Ottoman Caliphate, who was considered the leader of Sunni Muslims, as an effective political authority. It was a protest against the sanctions placed on the caliph and the Ottoman Empire after the First World War by the Treaty of Sèvres.
