After the establishment of British rule in India there was an enormous drain of wealth from India to Britain. This adversely affected the economy of India and country became poorer and poorer day by day. This drain began in the decades following the battle of Plassey in 1757.There was a constant flow of India's wealth out of the country with no returns at all. The British officials carried home immense fortunes extracted from the Indian people.
This kind of economic exploitation and the drain of Indian wealth formed the integral part of British policies. The exploitative character of British rule and its harmful impact on the lives of the Indians led to the rise of resentment and anti-British feelings in the minds of people. They tried to resist the imperialist and colonialist forces which had brought so much misery and hardship in their lives.
