The Khilafat Movement was a pan-Islamic political protest campaign launched by Muslims in British India between 1919-1924 to influence the British government and protect the Ottoman Empire after World War I. The movement gained strength after the Treaty of Sèvres in 1920 that partitioned the Ottoman Empire. Although mainly a religious movement, it became part of the wider Indian independence movement. The movement introduced religious rhetoric into Indian Muslim politics and gave Muslim clergy a central role in politics through organizations like the Jamiat-e-Ulama-e-Hind. It had a regressive ideological influence on modern Indian Muslim thinking.
