The resurgent Hindu Maratha Empire launched brutal raids against the prosperous Bengali state in the 18th century, which further added to the decline of the Nawabs of Bengal. A decade of ruthless Maratha invasions of Bengal from the 1740s to early 1750s forced the Nawab of Bengal to pay Rs. 1.2 million of tribute annually as the "Chauth" of Bengal and Bihar to the Marathas, and the Marathas agreed not to invade Bengal again. The expeditions, led by Raghuji Bhonsle of Nagpur, also established the "De facto" Maratha control over Orissa, which was formally incorporated in the Maratha Dominion in 1752. The Nawab of Bengal also paid Rs. 3.2 million to the Marathas, towards the arrears of chauth for the preceding years. The chauth was paid annually by the Nawab of Bengal to the Marathas up to 1758, until the British occupation of Bengal.
