By the time formal negotiations began, the situation had changed. The news of the British conquest of Havana and thus of the Spanish colony of Cuba had reached Europe. King Charles III of Spain refused to accept a treaty that would force Spain to cede Cuba, but the British Parliament would never ratify a treaty that did not reflect British territorial gains during the war. From 1774 to 1789, the Continental Congress served as the government of the 13 American colonies and later the United States. The first Continental Congress, composed of delegates from the colonies, met in 1774 in response to coercive laws, a series of measures. The diplomats concluded their negotiations and signed the preliminary Treaty of Paris on 3 November 1762. At the same time, Spanish and French negotiators signed the Treaty of San Ildefonso, which confirmed the cession of French Louisiana to Spain. Despite the unresolved border issues, the United States has benefited the most from the signatories of the treaties and has obtained recognition of its independence from the European powers. Although Britain lost its American colonies, British world power continued to grow, driven by the economic growth of the early Industrial Revolution.
For the France, victory came at a huge financial cost, and attempts to resolve the financial crisis would eventually spark the French revolution. On 5 August 1963, representatives of the United States, the Soviet Union and Great Britain signed the Treaty on the Limited Nuclear-Test-Ban Treaty, which prohibited the testing of nuclear weapons in outer space, underwater or in the atmosphere. The treaty signed by President John F. Kennedy signed . Franklin revealed the Anglo-American agreement to Vergennes, who opposed the way it had been obtained, but was willing to accept the agreement as part of broader peace negotiations, and agreed to grant the United States another loan that Franklin had requested. When Spanish forces failed to conquer Gibraltar, Vergennes managed to convince the Spanish government to accept peace as well. Negotiators abandoned an earlier complicated plan to redistribute the unconquered colonies into one colony that largely preserved existing Spanish and French territorial gains. In North America, Spain received Florida, which it had lost during the Seven Years` War. Representatives of Spain, France, the United Kingdom and the United States signed on 20 September. In January 1783, a provisional peace treaty announced the end of hostilities. The formal agreement was signed in Paris on September 3, 1783. The United States Confederate Congress ratified the treaty on January 14.
Britain violated the treaty provision that it should relinquish control of the forts on U.S. territory «at all proper speed.» British troops remained stationed in six forts in the Great Lakes region, plus two at the northern end of Lake Champlain. The British also built an additional fort in present-day Ohio in 1794 during the Northwest Indian War. They found their justification for these actions in the unstable and extremely tense situation that prevailed in the region after the war, in the failure of the United States government to fulfill obligations to compensate loyalists for their losses, and in the British need to have time to liquidate various assets in the region.  All posts were peacefully ceded by diplomatic means as a result of the Jay Treaty of 1794. After Yorktown, the Continental Congress appointed a small group of statesmen to travel to Europe and negotiate a peace treaty with the British: John Adams, Benjamin Franklin, John Jay, Thomas Jefferson, and Henry Laurens. The Treaty of Guadalupe Hidalgo, signed on February 2, 1848, ended the Mexican-American War in favor of the United States. The war had begun nearly two years earlier, in May 1846, over a territorial dispute between Texas. The contract added an additional 525,000 square miles to .
The actual geography of North America did not match the details used in the treaty. The treaty established a southern border for the United States, but the separate Anglo-Spanish Agreement did not establish a northern border for Florida, and the Spanish government assumed that the border was the same as in the 1763 agreement by which they first ceded their territory in Florida to Britain. As this controversy in West Florida continued, Spain used its new control over Florida to block U.S. access to the Mississippi River, in defiance of Article 8.  The treaty stipulated that the U.S. border extended directly west from the «most northwestern point» of Lake of the Woods (now partly in Minnesota, partly in Manitoba and partly in Ontario) to the Mississippi River. But in fact, the Mississippi River doesn`t extend that far north; The line that flows west of Lake of the Woods never crosses the river. Moreover, the Treaty of Paris did not explain how the new border would work in terms of controlling the movement of people and trade between the Canadian colonies of Great Britain and the United States. The expectation of American diplomats to negotiate a trade treaty with Britain that would resolve some of the unfinished business of the Treaty of Paris did not materialize in 1784; The United States waited a decade to negotiate its first trade agreement with the British Empire with the Jay Treaty. As far as the American Treaty is concerned, the key episodes occurred in September 1782, when French Foreign Minister Vergennes proposed a solution that was firmly rejected by his ally, the United States. The France was exhausted by the war, and everyone wanted peace except Spain, which insisted on continuing the war until it could conquer Gibraltar from the British. Vergennes found the agreement that Spain would accept instead of Gibraltar. The United States would gain independence, but would be limited to the region east of the Appalachian Mountains. Britain would retain the area north of the Ohio River, which was part of the province of Quebec. In the region south of it, an independent Indian barrier state would be established under Spanish control.  Despite apparent success, the Treaty of Paris eventually fostered disagreements between the Anglo-American settlers and the British government because their interests in North America no longer coincided. .
