The British controlled most of India but faced unrest from Indians who believed the British were trying to force Christianity on them and take their land. Economic problems and nationalism led some Indian soldiers in the British army to rebel against their poor treatment and low pay. The rebellion grew until open conflict broke out in 1857 across many regions of India, particularly in Delhi, due to grievances like racism and imperialism. Eventually British rule of India was reformed with a new government system established in 1877.
