Within hundred years of assuming the Diwani of Bengal, the British became the unquestioned rulers over a large part of the Indian subcontinent. They rarely had to use force to take control over a territory. They were doing profitable trade which was their main objective. They also succeeded in winning the support of most of the local rajas and chieftains. These are some of the possible reasons for the confidence of the British rulers about their position in India before May 1857.
