Explanation:

Nanasaheb had greatly expanded the Maratha Empire and had tried to establish better governance. However, he was held partially responsible for the severe defeat of the Marathas by Ahmad Shah Abdali at the Third Battle of Panipat in early 1761. The Maratha forces suffered heavy losses including Nanasaheb's eldest son and heir Vishwasrao Bhat and cousin Sadashivrao Bhau. He died on June 23, 1761 at Parvati in Pune.
