<Ul> <Li> This article settled a boundary dispute caused by ignorance of actual geography in the boundary agreed to in the 1783 Treaty of Paris that ended the American Revolutionary War . That earlier treaty had placed the boundary between the United States and British possessions to the north along a line going westward from the Lake of the Woods to the Mississippi River . The parties had failed to realize that the river did not extend that far north , so such a line would never meet the river . In fixing this problem , the 1818 treaty inadvertently created an exclave of the United States , the Northwest Angle , which is the small section of the present state of Minnesota that is the only part of the United States outside Alaska north of the 49th parallel . </Li> </Ul>
