![]() Alivardi Khan's successful usurpation of Bengal encouraged others to establish their rule. The Marathas were the earliest and the dangerous competitors. By the year 1740 Marathas had conquered most of central India. They were pushing their influence further. The north-eastern arm of the Maratha enabled one of their leaders, Raghuji Bhonsla, to conquer Berar thereby being able to send troops from there. In 1742 Raghuji Bhonsla sent his army through Orissa and into western Bengal. The Maratha troops plundered the west of the Hooghly up to Murshidabad. ![]() By the 1750s Orissa had been lost. The fabric of agreement on which the Nawab s' government rested was stretched so long as Alivardi Khan remained alive. The Marathas tried to establish their rule in western Bengal attract the leading zamindars but they could not succeed. Raghoji annexed Orissa and parts of Bengal and exploited the disorganized conditions that prevailed in the region post death of the Governor Murshid Quli Jafar Khan in 1727. The British East India Company began strengthening the defences at Fort William. Then the Nawab, Siraj -Ud -Daulah encouraged by the French attacked them. However under Robert Clive's leadership, British troops and their local allies captured Chandernagore in March 1757. Nawab was defeated on June 23, 1757 at the Battle of Plassey as Mir Jafar's soldiers betrayed him. He was assassinated in Murshidabad. The British established their own Nawab for Bengal. Chandernagore was restored to the French. There was an attempt by the Bengal rulers in alliance with Mughal Emperor Shah Alam II to regain their territories in 1765 but were defeated again at the Battle of Buxar(1765). |
