The Treaty of Paris was signed on September 3, 1783, officially ending the American Revolutionary War. The treaty recognized the independence of the American colonies and established borders for the new nation, which extended to the Mississippi River in the west, the Great Lakes to the north, and Florida to the south. This pivotal agreement not only marked the birth of the United States as a sovereign entity but also reshaped international relations in the Atlantic world. It provided a framework for future diplomatic negotiations and set a precedent for colonial independence movements, influencing history beyond the 18th century.
