The Khilafat movement (1919-1924) was an agitation by Indian Muslims allied with Indian nationalism in the years following World War I. Its purpose was to pressure the British government to preserve the authority of the Ottoman Sultan as Caliph of Islam following the breakup of the Ottoman Empire at the end of the war. Integral to this was the Indian Muslims’ desire to influence the treaty-making process following the war in such a way as to restore the 1914 boundaries of the Ottoman Empire. Hope this helps:)
