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.[3] The rebellion posed a considerable threat to British East Indian Company power in that region,[4] and it was contained only with the fall of Gwalior on 20 June 1858.[3] 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.[3] In Punjab, the Sikh princes backed the Company by providing both soldiers and support.[3] The large princely states, Hyderabad, Mysore, Travancore, and Kashmir, as well as the states of Rajputana did not join the rebellion.[5] In some regions, such as Oudh, the rebellion took on the attributes of a patriotic revolt against European presence.[6] Rebel leaders, such as the Rani of Jhansi, became folk heroes in the nationalist movement in India half a century
