Doctrine of Lapse: The policy through which Satara got annexed to East India Company.

Explanation:
Doctrine of Lapse was a policy introduced by Lord Dalhousie, Governor-General of India from 1848 to 1856, in which Indian states were annexed by the British East India Company if they had no male heir to succeed the throne. This policy was based on the assumption that Indian rulers were subordinate to British sovereignty, and if they failed to fulfill their duties to their subjects, the British had the right to take over their territory.

In the case of Satara, the last ruler, Pratap Singh, died without a male heir in 1848. According to the Doctrine of Lapse, the British East India Company annexed Satara, which was ruled by the Bhosle dynasty. This was one of the many states that were annexed by the British under this policy.

The Doctrine of Lapse was highly controversial as it was seen as an attack on Indian traditions and customs. Indian rulers who followed the policy of adoption to ensure a male heir were denied the right to do so. The policy was also seen as a violation of the sovereignty of Indian states and led to widespread resentment among Indian rulers and people.

Conclusion:
In conclusion, the Doctrine of Lapse was the policy through which Satara got annexed to the East India Company. This policy was introduced by Lord Dalhousie and led to the annexation of many Indian states by the British. The policy was highly controversial and seen as an attack on Indian traditions and customs.
