The historic agreement that ended the American Revolutionary War was the Treaty of Paris, signed in 1783. This treaty formally recognized the independence of the thirteen American colonies from British rule. Negotiated by American diplomats Benjamin Franklin, John Jay, and John Adams, the treaty laid out the boundaries for the new nation, granting the United States significant territorial gains. The Treaty of Paris was a crucial milestone, not only marking the end of the war but also setting the stage for the development of the United States as a sovereign nation with its own government and political aspirations.
