The Indian Rebellion of 1857 began as a mutiny of Indian soldiers (sepoys) in the East India Company's army on May 10, 1857 in Meerut, India. It marked the first major uprising against British rule in India and grew significantly, spreading to many parts of northern and eastern India. The rebellion was fueled by resentment of British control as well as religious and social grievances, and threatened British authority across wide areas of India until being suppressed by 1858. Key leaders in the rebellion included the Mughal emperor Bahadur Shah II and the Maratha leader Nana Saheb.
