Nana Sahib had a grievance against the British government because they refused to continue to him the pension of eight lakhs of rupees (-(80,000) which was promised to Baji Rao by Sir John Malcolm on his surrender in 1818.

The wazir then decided to annex their country, and appealed to Hastings for assistance, which was given in return for a sum of forty lakhs of rupees.
