The major treaty that officially ended the American Revolutionary War in 1783 is the Treaty of Paris. This treaty was signed on September 3, 1783, and recognized American independence from British rule. It marked a significant milestone in American history, establishing the boundaries of the new nation. The treaty also addressed various other issues, such as fishing rights and the restitution of property, and represented a turning point in global relations, as it set a precedent for colonial independence movements around the world. The success of the treaty affirmed the triumph of the American colonies and their aspirations for self-governance.
