Roseau County, Minnesota: History
Roseau County was once the home of many Ojibwe, Sioux, and Mandan tribes. Archeologists have found artifacts within the county belonging to these tribes that date back 7,200 years. More recent history includes fur trappers and European-based explorers. By 1822, a fur-trading post was established in the area. In 1885, the future Roseau City hosted four settlers; by 1895 there were 600, and the area was incorporated as Roseau.
By the mid-1880s the early settlers of eastern Kittson County were feeling the disadvantage of their location, far from the county seat, and petitioned the government for a separate county. On December 31, 1894, Governor Knute Nelson proclaimed the eastern portion of Kittson a new county, to be named Roseau. On February 11, 1896, the next governor, David Marston Clough, added part of Beltrami County to Roseau County. Roseau was named the county seat.
Until May 1965, when county option was eliminated, Roseau County was a dry county; no beverages with over 3.2% alcohol could be sold.
