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,[1][2] and Abul Kalam Azad[3] 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.[
