The massacre and Gandhi's non-violent response to it moved many, but also made some Sikhs and Hindus upset that Dyer was getting away with murder. Investigation committees were formed by the British, which Gandhi asked Indians to boycott.[1] The unfolding events, the massacre and the British response, led Gandhi to the belief that Indians will never get a fair equal treatment under British rulers, and he shifted his attention to swaraj and political independence for India.[125] In 1921, Gandhi was the leader of the Indian National Congress.[3] He reorganised the Congress. With Congress now behind him, and Muslim support triggered by his backing the Khilafat movement to restore the Caliph in Turkey,[109] Gandhi had the political support and the attention of the British Raj.[112][106][6]
