Convention of 1818 Signed

Convention of 1818 Signed

On October 20, 1818, representatives of the United States and Great Britain signed a convention in London. The terms of this agreement established the northernmost limits of the Louisiana Purchase by setting the boundary between the United States and Canada at the 49th parallel from the Lake of the Woods west to the crest of the Rocky Mountains. In addition the 1818 document provided that Oregon country, which lay west of the Rockies, would remain open to settlement by both American and British citizens for ten years without either nation's forfeiting its territorial claim in the Pacific Northwest.

The convention of 1818 also dealt with matters not directly related to territorial disputes. One article granted American citizens fishing rights in the coastal waters of Labrador and Newfoundland. Another renewed the commercial agreement of 1815 that permitted the United States to trade in the East Indies and ended discriminatory duties on imported goods.
