where did we get the northwest territory from
Northwest Territory The region was assigned to the United States in the Treaty of Paris of 1783, but sporadic westward emigrant settlements had already resumed late in the war after the Iroquois Confederacy's power was broken and the tribes scattered by the 1779 Sullivan Expedition. Soon after the Revolution ended, land-hungry migrants started moving west. A gateway trading post developed as the town of Brownsville, Pennsylvania, which was a key outfitting center west of the mountains. Other wagon roads, such as the Kittanning Path surmounting the gaps of the Allegheny in central Pennsylvania, or trails along the Mohawk River in New York, enabled a steady stream of settlers to reach the near west and the lands bordering the Mississippi.[a] This activity stimulated the development of the eastern parts of the eventual National Road by private investors. The Cumberlandâ€“Brownsville toll road linked the water routes of the Potomac River with the Monongahela River of the Ohio/Mississippi riverine systems in the days when water travel was the only good alternative to walking and riding. Most of the territory and its successors was settled by emigrants passing through the Cumberland Narrows, or along the Mohawk Valley in New York State.
49th parallel north Roughly 3,500 kilometres (2,175 mi) of the Canada–United States border was designated to follow the 49th parallel from British Columbia to Manitoba on the Canada side, and from Washington to Minnesota on the U.S. side, more specifically from the Strait of Georgia to the Lake of the Woods. This international border was specified in the Anglo-American Convention of 1818 and the Oregon Treaty of 1846, however the border as indicated by survey markers placed in the 19th century deviates from the 49th parallel by tens of meters.
