These internal conflicts would lead Siraj-ud-Daula to hastily annex Calcutta from the English East India Company, without the permission of the Mughal Emperor Alamgir II and Salabat Jung. Siraj-ud-Daula was quickly defeated by Clive who recaptured Calcutta and defeated Siraj-ud-Daula during the Battle of Plassey in the year 1757.
