The British East India Company expanded its control over most of India as the Mughal Empire declined. By the 1850s, the Company ruled India and maintained control through its Indian army, made up of sepoy soldiers. However, in 1857, sepoys rebelled against new Enfield rifles that required biting cartridges greased with animal fat, sparking the Sepoy Mutiny against British rule. The rebellion was crushed, and Britain took direct control over India as resentment between Indians and the British increased.
