Maratha invasions of Bengal
The Maratha invasions of Bengal (1742–1751), were a series of raids by the Maratha forces in the Bengal Subah (Bengal, Bihar, parts of modern Orissa), after the successful campaign in the Carnatic region at the Battle of Trichinopoly. The campaigns were carried out under Raghuji I of Nagpur.
