Causes of 1857 Revolt -
1. Social and Religious Causes: The British had abandoned its policy of non-interference in the socio-religious life of the Indians.
2. Economic Causes: British rule led to the breakdown of the village self-sufficiency, commercialization of agriculture which burdened the peasantry, adoption of free trade imperialism from 1800, de-industrialization, and drain of wealth all of which led to the overall decline of the economy.
3. Military Grievances: The extension of British dominion in India had adversely affected the service condition of the Sepoys.
4. Political Causes: The last major extension of the British Indian territory took place during the time of Dalhousie.
