The Revolt of 1857 was the first major challenge to British rule in India. It was caused by exploitative colonial policies that hurt Indian agriculture, increased taxes, and limited employment. Religious and political reforms antagonized many. The revolt began with soldier mutinies over rumors about new gun cartridges and bread. It spread from Meerut to Delhi and other major cities, with Bahadur Shah Zafar declared the emperor. Though some civilians joined, there was no true all-India revolt or central leadership. The British used superior weapons and leadership to eventually suppress the revolt in major cities by September 1857.
