What could be the reasons for the confidence of the British rulers about their position in India before May 1857?

The British became confident about their position in India because of the following reasons:

1. The Mughal rulers, after the death of Aurangzeb, were not strong and powerful. Hence, it was easier for the British to annex states.
2. The disunity between nawabs and the Mughal rulers helped the British have a firm stronghold over Indian society, starting from Bengal.
3. The policies, like Subsidiary Alliance, helped the British annexe territories one after another, without the use of any military power.
4. The revolt of 1857 was crushed by the British, leading to their supremacy over Indian society.
