The Maratha invasions of Bengal (1742–1751), were the 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 Raghoji Bhonsle of Nagpur. Between April 1742 to March 1751, the Marathas invaded Bengal many times, causing widespread economic losses in the Bengal Subah.
