Third Anglo-Maratha War (1817-1818) Maratha made a desperate last attempt to regain their independence and prestige in 1817.This led in organizing a united front of the Maratha Chiefs and was taken over by the Peshwa who was uneasy under the rigid control exercised by the British Resident. However once again the Marathas failed to evolve any plan of action. The Peshwa attacked the British Residency at Poona in 1817, Appa Saheb of Nagpur attacked the Residency at Nagpur and Madhav Rao Holkar made preparations for war.
The Maratha confederacy was altogether destroyed so many territories were taken from its various members that they were rendered powerless to do anything against the British. Thus the work was accomplished by Lord Hastings in 1818.Now the British Government became the supreme and paramount authority in India
