Explanation:

The Treaty of Purandar was signed on June 11, 1665, between the Rajput ruler Jai Singh I, who was commander of the Mughal Empire, and Maratha Chhatrapati Shivaji Maharaj.Chhatrapati Shivaji was forced to sign the agreement after Jai Singh besieged Purandar fort. When Chhatrapati Shivaji realised that war with the Mughal Empire would only cause damage to the empire and that his men would suffer heavy losses, he chose to make a treaty instead of leaving his men under the Mughals.
