The Treaty of Bassein (Now called Vasai) was a pact signed on 31 December 1802 between the British East India Company and Baji Rao II, the Maratha peshwa of Pune (Poona) in India after the Battle of Poona.
On 13 May 1803, Baji Rao II was restored as peshwa under the protection of the East India Company.
The treaty was not acceptable to all Marathas chieftains, and resulted in the Second Anglo-Maratha War.
The terms of the treaty entailed the following—-
A British force of around 6,000 troops be permanently stationed with the peshwa.
Any territorial districts yielding 2.6 million rupees were to be paid to the East India Company.
The peshwa could not enter into any other treaty without first consulting the Company.
The peshwa could not declare war without first consulting the Company.
The peshwa must renounce his claim over Surat and Baroda.
The peshwa must exclude all Europeans from his service.
