Jinnah broke with the Congress in 1920 when the Congress leader, Mohandas Gandhi, launched a law violating Non-Cooperation Movement against the British, which a temperamentally law abiding barrister Jinnah disapproved of. Unlike most Congress leaders, Gandhi did not wear western-style clothes, did his best to use an Indian language instead of English, and was deeply rooted to Indian culture. Gandhi’s local style of leadership gained great popularity with the Indian people. Jinnah criticised Gandhi’s support of the Khilafat Movement, which he saw as an endorsement of religious zealotry. By 1920, Jinnah resigned from the Congress, with a prophetic warning that Gandhi’s method of mass struggle would lead to divisions between Hindus and Muslims and within the two communities. Becoming president of the Muslim League, Jinnah was drawn into a conflict between a pro-Congress faction and a pro-British faction.
