The Doctrine of Lapse was an annexation policy followed widely by Lord Dalhousie when he was India’s Governor-General from 1848 to 1856.
- According to this, any princely state under the direct or indirect (as a vassal) control of the East India Company where the ruler did not have a legal male heir would be annexed by the company
- As per this, any adopted son of the Indian ruler could not be proclaimed as heir to the kingdom. This challenged the Indian ruler’s long-held authority to appoint an heir of their choice.
