Introduction:
The Doctrine of Lapse was a policy implemented by the British East India Company in India during the 19th century. It was a controversial policy that allowed the Company to annex states that did not have a male heir to the throne.

Explanation:
- The Doctrine of Lapse was first introduced by Lord Dalhousie, the Governor-General of India, in the mid-19th century.
- According to this policy, if a ruler of a princely state died without a male heir, the state would be annexed by the British East India Company.
- This policy was seen as a way for the Company to increase its control over India and expand its territories.
- Many Indian rulers were unhappy with the Doctrine of Lapse, as it threatened their independence and sovereignty.
- The policy was particularly controversial because it went against the traditional Indian practice of allowing rulers to adopt male heirs to ensure the continuity of their dynasties.

Conclusion:
In conclusion, the Doctrine of Lapse was a significant policy that had far-reaching consequences for the princely states of India. It was a controversial policy that led to the annexation of several states by the British East India Company. While the policy was eventually abolished, its impact on the political landscape of India during the 19th century cannot be understated.
