20 oct 1818 año - Treaty of 1818

Descripción:

A treaty signed between the US and the UK primarily to settle boundary disputes. It allowed for the joint occupation of the Oregon Country for 10 years. It also set the national border along "a line drawn from the most northwestern point of the Lake of the Woods, [due south, then] along the 49th parallel of north latitude..." to the "Stony [Rocky] Mountains." In doing this, the UK ceded the part of Rupert's Land and Red River Colony below the line (containing parts of modern-day Minnesota, North Dakota, South Dakota, and a bit of Montana), while the US ceded a small portion of the Louisiana Purchase above the line.
