The Treaty of Paris, signed in 1783, established peace between the United States and Great Britain, formally ending the American Revolutionary War. The treaty was negotiated primarily by American diplomats, including Benjamin Franklin, John Adams, and John Jay, and it recognized the independence of the thirteen American colonies. It also defined the boundaries of the new nation, granting the U.S. territory from the Atlantic Ocean to the Mississippi River. This treaty marked a significant milestone in American history, solidifying the U.S. as a sovereign state and paving the way for westward expansion.
