5th Earl of Selkirk acquired controlling interest in the HBC and received 116,000 square miles of land in the Selkirk Concession of 1811. The area of land within the grant became known as the Assiniboia Territory, and extended south to the watershed of the Red River near the 45th parallel north. The current community of Pembina was within the area. Treaties The Treaty of Paris (1783) did not clearly set northern United States/Canadian boundaries. According to the treaty the boundary line was to leave the Northwesternmost point of the Lake of the Woods (the current boundary) "on a due West Course to the river Mississippi" which is much farther south. Jay Treaty (1796) boundaries issues were still unresolved in 1801. The Treaty of Ghent (1814-1815). The Rush–Bagot Treaty (April 16, 1818) was a treaty of disarmament and peaceful negotiations creating a demilitarized boundary. The following Treaty of Washington (1871) set up peaceful international arbitration. Indian treaties further open land to expansion and this was the beginning of the seeking of territorial status. The Treaty of 1818 (October 20, 1818) was a land swap trading British land that extended south of the new 49th parallel boundary for US land that extended north of the border. This area was originally part of the Louisiana Purchase, and was renamed the Missouri Territory in 1812. The territorial government seat was in St. Louis. After a border survey in 1823, the Hudson's Bay Company could not continue to assume that Pembina stood on British soil and moved into southern Canada. Territory of Minnesota After 1849, the region of Pembina became part of the Territory of Minnesota. When Minnesota became a state in 1858 the area became unorganized again. A provisional government was set up that lobbied for territory status. The main reason to organize the area was to induce settlement with a more localized government. After the Dakota Territory was organized there was still a move for more local territorial control because of the distance to the territorial capital. Factions were attempting this in different areas of the territory. South Dakota introduced legislation, with the support of the Committee on Territories, for the creation of the West and East River Territories. In 1868, after the discovery of gold in the Black Hills (1876), there was a proposal to separate the western half into the "Territory of Lincoln" and the eastern half as the Dakota Territory.
