The American Revolution officially ended when representatives of the United States, Great Britain, Spain and France signed the Treaty of Paris on that day in 1783. The signing meant the status of a free nation of America, as Britain officially recognized the independence of its 13 former American colonies and the borders of the new Republic were agreed: Florida north of the Great Lakes and the Atlantic coast west of the Mississippi River. The events leading up to the treaty date back to April 1775 on a common green in Lexington, Massachusetts, when American settlers responded to King George III`s refusal to grant them political and economic reforms with the armed revolution. Franklin revealed the Anglo-American agreement to Vergennes, which opposed the manner in which it was obtained, but was willing to accept the agreement in broader peace negotiations and agreed to provide the United States with another loan that Franklin had requested. When Spanish forces failed to conquer Gibraltar, Mr. Vergennes managed to convince the Spanish government to approve the peace. Negotiators abandoned a previous complex plan to redistribute undefeated colonies into a colony that largely preserves the existing territorial benefits of Spain and France. In North America, Spain received Florida, which it had lost during the 7-year war. Spanish, French, British and American representatives signed a provisional peace treaty on 20 January 1783 that heralded the end of hostilities. The formal agreement was signed in Paris on September 3, 1783. The Congress of the American Confederation ratified the treaty on January 14.
The actual geography of North America did not match the details used in the contract. The treaty established a southern border for the United States, but the separate Anglo-Spanish agreement did not provide for a northern border for Florida, and the Spanish government assumed that the border was the same as in the 1763 agreement, by which they had first ceded their territory in Florida to Britain. As the West Florida controversy continued, Spain used its new control over Florida to block U.S. access to Mississippi, in defiance of Article 8.  The treaty stipulated that the U.S. border extended directly westward from the “most northwest point” of Wood Lake (now partially to Minnesota, partly to Manitoba and partly to Ontario) until it reached the Mississippi River.
