Jhansi was annexed by the British in 1854 under the Doctrine of Lapse, a policy implemented by Lord Dalhousie. This policy stated that any princely state under the influence of the British would be annexed if the ruler died without a natural heir. The refusal to recognize the adopted son of the Raja of Jhansi led to the state's annexation and Rani Lakshmibai's subsequent role in the 1857 revolt.
