The document signed to end the American Revolutionary War was the Treaty of Paris (1783). Negotiated primarily by American representatives Benjamin Franklin, John Adams, and John Jay, the treaty formally recognized the independence of the thirteen American colonies from British rule. It outlined the boundaries of the new nation, granting large territories to the United States west of the Appalachian Mountains. The Treaty of Paris marked a significant milestone in American history, establishing principles of self-governance and individual rights. It set the stage for the development of the United States and its expansion in the following years.
