Alamgir II
Alamgir II grieved the death of Alivardi Khan the famous Nawab of Bengal, who annually pledged 5 million "dams" to the imperial court. His successor Siraj-ud-Daula was recognised as the next Nawab of Bengal, but he faced internal rivals who refused to consider the Firman granted by Alamgir II to Siraj-ud-Daula. 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. After the annihilation of his entire army Siraj-ud-Daula fled and was killed by the forces of the treacherous Mir Jafar. The deceased Siraj-ud-Daula's pretensions were criticised in the Mughal imperial court by Ghulam Husain Tabatabai, and Alamgir II refused to recognise Mir Jafar as the next Nawab of Bengal. In response to the imperial court's decision Mir Jafar thus consolidated and alliance with the manipulative Imad-ul-Mulk against the imperial family.
