The Maratha empire expanded between 1720 and 1761. It gradually chipped away at the authority of the Mughal Empire. Malwa and Gujarat were seized from the Mughals by the 1720s. By the 1730s, the Maratha king was recognised as the overlord of the entire Deccan peninsula.
After raiding Delhi in 1737 the frontiers of Maratha domination expanded rapidly — into Rajasthan and the Punjab in the north, into Bengal and Orissa in the east, and into Karnataka and the Tamil and Telugu countries in the south. These were not formally included in the Maratha empire, but were made to pay tribute as a way of accepting Maratha sovereignty.
