The Indian Rebellion of 1857 was a revolt of a portion of the Indian Army. It was characterized by massacres of civilians on both sides. It was not a movement for independence, however, and only a small part of India was involved. In the aftermath, the British pulled back from modernizing reforms of Indian society, and the level of organised violence under the British Raj was relatively small. Most of that was initiated by repressive British administrators, as in the Amritsar massacre of 1919, or the police assaults on the Salt March of 1930. Large-scale communal violence broke out between Muslims and Hindus and Muslims and Sikhs after the British left in 1947 in the newly independent dominions of India and Pakistan
