Under a 1854 Treaty of La Pointe the Fond du Lac Indian Reservation and other reservations were established in exchange for all the Lake Superior Ojibwe land in the Arrowhead Region. Carlton County was formed and organized in 1870.[8] It was named for Reuben B. Carlton, a member of the Minnesota Senate (1857–58).[9]
In October 1918, an immense forest fire occurred, known as the Cloquet fire. The Carlton County Historical Society hosts a permanent exhibit about the fire of 1918, along with ones about the Ojibwe of Carlton County and the Logging Era.[10]

Government and politics
Local government
As of 2019, the Carlton County Sheriff is Kelly Lake.[20] The Carlton County Board of Commissioners has five members, each representing one district.[21] In April 2019 Lake and the Fond du Lac Police Department collaborated on sex trafficking training on behalf of other sheriff agencies that would be affected by the upcoming Enbridge Line 3.[22] In 2017, Carlton County published a detailed Jail & Criminal Justice System Planning Study.[23] As of 2019, Carlton County Public Health employs 36 county staff and 6 contract staff. It has been operating since 1920.[24]
National
The Democratic Party historically dominated the county, carrying it by wide margins in every presidential election from 1932 to 2012, but Donald Trump lost by only 300 votes in 2016 and 307 votes in 2020 (a margin of under 2% and holding the Democrats to only a plurality in both elections), signaling a new competitiveness in Carlton County. The only other Republican to receive at least 40% of the vote since 1932 was Richard Nixon during his 49-state landslide in 1972. During the 2022 Midterm Elections, the Republican candidates for Attorney General and State Auditor won Carlton County,[25] and Republicans also flipped State House District 11A,[26] which includes most of Carlton County and came among other seat flips on the Iron Range despite not winning the State House overall.[27] These wins marked a potential realignment towards the Republican Party. This trend continued in 2024, with Donald Trump becoming the first Republican since Herbert Hoover in 1928 to win the county, receiving 50.13% of the vote.[28]
