The Red River Colony was a colonization project set up in 1811 by Thomas Douglas, 5th Earl of Selkirk on 300000km2 of land. This land was granted to him by the Hudson's Bay Company, which is referred to as the Selkirk Concession. The establishment of Canada in the late 19th century led to the creation of what is today Manitoba, although much of its original territory is now part of the United States.The Selkirk Concession, also known as Selkirk's Grant, included the portions of Rupert's Land, or the watershed of Hudson Bay, bounded on the north by the line of 52° N latitude roughly from the Assiniboine River east to Lake Winnipegosis. It then formed a line of 52°30′ N latitude from Lake Winnipegosis to Lake Winnipeg, and by the Winnipeg River, Lake of the Woods and Rainy River. On the west of the Selkirk Concession, it is roughly formed by the current boundary between Saskatchewan and Manitoba. These covered portions consist of present-day southern Manitoba, northern Minnesota, and eastern North Dakota, in addition to small parts of eastern Saskatchewan, northwestern Ontario, and northeastern South Dakota.
