The Treaty of Paris, signed in 1783, was significant for the United States as it officially ended the American Revolutionary War. This treaty recognized the independence of the United States from British rule and established its boundaries, extending from the Atlantic Ocean to the Mississippi River. It granted rights to fishing off the coast of Newfoundland and addressed various issues regarding debts and the loyalists. The treaty marked a turning point in American history, allowing the fledgling nation to establish its identity and governance separately from Britain, and laid the groundwork for future diplomatic relations and territorial expansion.
