The Khilafat Movement was launched in 1919 by Muslims in British India to influence the British government and protect the Ottoman Empire after World War 1. It gained support when the Ottoman Empire faced losing territory. Congress initially cooperated with Khilafat leaders to demand self-rule for India. However, the movement weakened as Muslims disagreed on supporting Congress, Khilafat, or the Muslim League. It ultimately collapsed in 1924 when the Ottoman caliphate was abolished by Kemal Ataturk's secular Turkish government. While failing its goal, Khilafat had lasting impacts like strengthening Muslim political identity and the two-nation theory in India.
