This map by Henry D. Pursell shows the United States as it was in 1784,shortly after the American Revolution. This map marks the beginning of settlement into the Old Northwest, the land west of the Appalachian Mountains. Around the creation of this map, Congress passed the Land Ordinance of 1784, which divided the Northwest into ten territories. The tentative names of these territories are shown, with Michigan being labeled as Michigania, the Ohio area as Metropotamia, and Illinois as Illinoia.
