Encyclopædia Britannica - Treaty of PurandharAfter the death of the peshwa Narayan Rao in 1773, his uncle Raghunath Rao tried to secure the succession.Raghunath's claim in the Treaty of Surat (7 March 1775) in return for Salsette Island and Bassein (Vasai). But the supreme government disallowed this treaty and sent its own agent to renegotiate. The resulting Treaty of Purandhar annulled that of Surat. Raghunath was pensioned and his cause abandoned, but Salsette and the Broach revenues were retained by the British. The tangle was increased by the support of the London authorities for Bombay, which in 1778–79 again supported Raghunath. Peace was finally restored in 1782.
