The Lucknow Pact of 1916 saw the Muslim League and Indian National Congress agree to cooperate in demanding self-rule from the British. The pact conceded that Muslims were a separate nation and guaranteed seats for minority religious groups in provincial legislatures. Muhammad Ali Jinnah negotiated the pact and was hailed as the "Ambassador of Hindu-Muslim unity." Meanwhile, the Khilafat Movement sought to maintain the status of the Ottoman Caliph and protect Muslim holy sites after World War I, uniting Muslims and Congress. Though it failed to achieve its goals and ended with communal violence, the movement politically awakened Muslims and eroded trust in both the British and Hindus.
