Question

what were the effects of the doctrine of lapse analyse

Answer 1

Awadh (1856) is widely believed to have been annexed under the Doctrine of Lapse. However it was annexed by Lord Dalhousie under the pretext of mis-governance. ... Dalhousie's annexations and the doctrine of lapse had caused suspicion and uneasiness among most ruling princes in India.

Answer 2

The Doctrine of Lapse was not successful because it was instrumental in annexing so many important kingdoms. It wasn't coincidental. Rather the policy was designed in such a manner that it could apply to most areas and set the ground for the British annexing majority of kingdoms. The policy was managed to suit the needs. For instance, Oudh (Awadh) did have a legal heir, Wajid Ali Shah, but Company rule was extended to Oudh on grounds of mal-administration. It was in fact stated that the Company was doing good to the people of Oudh by freeing them from the mal-administrator Nawabs.
