India strongly supported the Empire in the First World War. It expected a reward, but failed to get home rule as the British Raj kept control in British hands and feared another rebellion like that of 1857. The Government of India Act 1919 failed to satisfy demand for independence. Mounting tension, particularly in the Punjab region, culminated in the Amritsar Massacre in 1919. Nationalism surged and centred in the Congress Party led by Mohandas Gandhi. In Britain public opinion was divided over the morality of the massacre, between those who saw it as having saved India from anarchy, and those who viewed it with revulsion.
