Explanation:
The Third Anglo-Maratha War was the final and decisive conflict between the British East India Company and the Maratha Empire. After the Marathas attempted to resist British influence in India and sought to restore their power, the British declared war. The conflict saw a series of battles, culminating in the Battle of Koregaon, where the British decisively defeated the Marathas. The Peshwa, Baji Rao II, was defeated and exiled to Bithoor. The Maratha Empire effectively ceased to exist, and the British became the undisputed rulers of most of India, marking the end of Maratha power and the establishment of British hegemony.
