The Doctrine of Lapse was a policy introduced by the British East India Company in the 19th century. According to this doctrine, if a ruler of a Princely State died without a natural heir, the state would be annexed by the British Empire. This policy was used to expand British control over the Indian subcontinent.

When the last ruler of Satara, Shahaji II, died without a natural heir in 1848, the British used the Doctrine of Lapse to annex the state and bring it under British control.
