Mahadaji Shinde captured Delhi on the 10th of February 1771. The Maratha army entered the city with 3,000 cavalry and slaughtered the Rohilla defenders who had held the capital since the Third Battle of Panipat.
Mahadaji Shinde demanded 40 lakhs of rupees to restore Shah Alam II to his throne. The Maratha chiefs also required the cession of Meerut and neighboring districts and claimed half of the nazar tribute paid to the emperor.
Mahadaji Shinde attacked the Rohillas in 1772 to punish them for their role in the Third Battle of Panipat. The campaign targeted Zabita Khan and aimed to erase the memory of Rohilla resistance while securing Maratha dominance in western Uttar Pradesh.
The Third Battle of Panipat in 1761 was a catastrophic defeat that shattered Maratha dominance in northern India. The loss left the confederacy vulnerable to Afghan and Rohilla aggression and caused internal instability following the death of Peshwa Balaji Bajirao.
Saif-ud-din Muhammad Khan accepted the harsh terms imposed by Mahadaji Shinde on behalf of the Mughal court. He forwarded the demands for ratification despite the crushing nature of the financial and territorial concessions required.
