The Khilafat movement was launched in British India in 1919 to preserve the Ottoman Caliphate and Muslim control over holy sites after World War I. Hindus and Muslims collaborated in mass demonstrations and boycotts to pressure the British. The movement's goals were to keep the Ottoman Khilafat intact, preserve its territories, and ensure non-Muslim control over holy places. Though popular and involving leaders like Gandhi, the movement declined after violence in 1921-1922 and the abolition of the Caliphate in 1923, exposing divisions between Hindus and Muslims.
