Saint Louis County was founded on February 20, 1855, as Doty County, and had its name changed to Newton County on March 3, 1855. It originally consisted of the area east and south of the Saint Louis River, while the area east of the Vermilion River and north of the Saint Louis River was part of Superior County. Superior County was renamed Saint Louis County. Then on March 1, 1856, that Saint Louis County became Lake County, and Newton County was renamed Saint Louis County and had that eastern area added to it; it was also expanded westward by incorporating parts of Itasca County, which then also included most of Carlton County. On May 23, 1857, Saint Louis County took its current shape when Carlton County was formed from parts of Saint Louis and Pine counties.
