The main conflict occurred largely in the upper Gangetic plain and central India, with the major hostilities confined to present-day Uttar Pradesh, Bihar, northern Madhya Pradesh, and the Delhi region. The rebellion posed a considerable threat to British East Indian Company power in that region, and it was contained only with the fall of Gwalior on 20 June 1858. Some[who?] regard the rebellion as the first of several movements over ninety years to achieve independence, which was finally achieved in 1947.
Other regions of Company-controlled India—Bengal province, the Bombay Presidency, and the Madras Presidency—remained largely calm. In Punjab, the Sikh princes backed the Company by providing both soldiers and support. The large princely states, Hyderabad, Mysore, Travancore, and Kashmir, as well as the states of Rajputana did not join the rebellion.
