The treaty that you are asking about in this question is typically known as Jay’s Treaty. It is also known as Jay’s Treaty of 1794. This treaty was agreed to by the United States, which had just become independent, and Great Britain.
The American colonies, of course, fought against Great Britain in the Revolutionary War. The war lasted from 1775 until 1781. After the war ended with the United States becoming independent, there were still issues on which the two countries were in conflict. John Jay was the first Chief Justice of the Supreme Court of the United States. He had also served as an American ambassador to Spain and France during the Revolutionary War. This experience, along with his generally pro-British attitudes, led President Washington to appoint him to negotiate a treaty with Great Britain that would help to resolve the outstanding issues between the two countries.
The parts of Jay’s Treaty that had to do with Native American/First Nations rights are not very well-known. The treaty did recognize that the natives of the US and Canada had tribal affiliations that crossed the newly-made border. Therefore, the treaty provided that First Nations people could cross the border to work and for other purposes. Thus, the treaty that you are looking for is Jay’s Treaty of 1794.
