Ratified by the Senate in 1797. Chief Justice John Jay negotiated this treaty with Great Britain. Under Jay's Treaty, the British agreed to leave areas in the Northwest Territory which they had been required to return earlier, under the Treaty of Paris. This treaty did not, however, oblige the British to observe American neutral rights. Despite the fact that Jay's Treaty was very unpopular, it was ratified by the Senate: 20-10. For the next fifteen years, the United States benefited from the treaty greatly.
