The Second Anglo-Maratha War (1803-1805) was a conflict between the British East India Company and the Maratha Empire in India. The war arose from tensions over territorial control and alliances, particularly after the Treaty of Bassein in 1802, which favored British interests. The British aimed to expand their influence in India, while the Marathas sought to maintain their sovereignty. The war involved several key battles, including the Battle of Assaye and the Battle of Argaon, where British forces, led by Arthur Wellesley, achieved significant victories. Ultimately, the conflict ended with the Treaty of Delhi in 1805, which solidified British power in India and reduced the Maratha influence.
