A map showing how North America was divided after the Treaty of Paris in 1783.
The treaty formally ended the American Revolutionary War and forced Britain to recognize the independence of the United States. The new country stretched west to the Mississippi River, north toward the Great Lakes, and south to the border with Spanish Florida.
Spain also came out of the wider peace settlement with major gains. It regained East and West Florida from Britain and already controlled Louisiana west of the Mississippi, giving it a huge presence across the south and west of the continent.
Britain, meanwhile, kept Canada and its northern possessions. France had already lost most of its North American empire in 1763, but it still retained the tiny islands of Saint-Pierre and Miquelon off Newfoundland, which remain French territory today.
Vermont is one of the more unusual details on the map. It had declared itself an independent republic in 1777 and remained separate until joining the United States as the 14th state in 1791, although its status was disputed during that period.
The borders agreed on paper were not always settled immediately on the ground. Britain continued occupying several forts in the Great Lakes region for years after the treaty, while the United States and Spain argued over the northern boundary of West Florida until a later agreement in 1795.
Some boundaries were also based on incomplete geographic knowledge, meaning the political map of North America was still far from final.
The result was a continent where the newly independent United States existed alongside much larger British and Spanish possessions, with several borders and territorial claims still waiting to be resolved.
