The concluding document that ended the Peace of Paris negotiations following the Revolutionary War was the Treaty of Paris, signed on September 3, 1783. This treaty officially recognized the independence of the United States and established boundaries for the new nation. The agreement was pivotal in resolving outstanding issues between the U.S. and Great Britain, including fishing rights and the return of property seized during the war. The treaty laid the foundation for American sovereignty and marked a significant shift in power dynamics, as it was the first time a British colony successfully achieved independence, influencing later decolonization movements worldwide.
