Convention of 1818
CONVENTION OF 1818
On October 20, 1818, a convention was signed by the United States and Britain which established part of the present-day border between the United States and Canada. The agreement stipulated that 49 degrees north latitude (or the 49th parallel) would mark the boundary, from Lake of the Woods (in present-day northern Minnesota, southwestern Ontario, and southeastern Manitoba) west to the Rocky Mountains (in present-day Montana and Alberta). The two countries further agreed that for 10 years they would jointly occupy the Pacific Northwest territories—the area that begins at 42 degrees north latitude (the southern boundary of present-day Oregon) and extends north to 54 degrees 40 minutes north latitude (in present-day British Columbia). However, even before the agreement was made, and even before the United States and Britain had fought the War of 1812 (1812–1814), American expansionists had begun to demand the seizure of Canada from Great Britain. Thus, after the eastern boundary had been established by the Convention of 1818, expansionists began to suggest that the Pacific Northwest territories ought to be part of a strategic claim made by the United States.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
