Answer 2

The doctrine of lapse was introduced by  Lord Dalhousie in India before 1858. It was a policy of annexation for the Indian Princely states. The idea of the doctrine was that if any of the Princely states of India has no legal male heir, would be annexed by the company. As a result of this doctrine, many of the Indian princely states lost their sovereignty.

The British East India Company gently and gradually developed its trading ventures in India by getting approval from the then ruling authorities, the Mughals and the regional governors. The EEIC adopted a threefold strategy of military, ideological and colonial administrative apparatus to develop and solidify the British Indian Empire. For instance they adopted the policy of subsidiary alliance, outright wars.
