The crucial agreement by which Shivaji was compelled to surrender forts to the Mughals was the Treaty of Purandar, signed in 1665 AD. The treaty was negotiated with the Mughal general, Raja Jai Singh I, whom Emperor Aurangzeb had sent to subdue the Maratha leader. Under the terms, Shivaji was required to cede twenty-three of his most important forts and territories and pay tribute. This treaty was a major political victory for the Mughals, demonstrating their military pressure, although Shivaji quickly recovered his power and forts soon after the agreement.
