The British and American committees that met after the War of 1812 to resolve boundary disputes recognized there would be much animosity in surveying the watershed boundary, and agreed on a simpler border solution in 1818: the 49th parallel. However, it is often difficult to precisely determine the location of a watershed in a region of level plains, such as in central North America. Historyįollowing the Louisiana Purchase by the United States in 1803, it was generally agreed that the boundary between the new territory and British North America was along the watershed between the Missouri River and Mississippi River basins on one side and the Hudson Bay basin on the other.

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 Canadian side, and from Washington to Minnesota on the U.S. Its main airport, Charles de Gaulle Airport, lies on the parallel. The city of Paris is about 15 km (9 mi) south of the 49th parallel and is the largest city between the 48th and 49th parallels. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. The 49th parallel north is a circle of latitude that is 49 degrees north of the Earth's equatorial plane.
