History

The county was created by the Minnesota Territory legislature on May 23, 1857, with Fair Mount (which was also platted in 1857) designated as county seat. The town’s name was later shortened to Fairmont. Two explanations have been advanced for the county’s name. A delegate to the US Congress from the Wisconsin Territory, Morgan Lewis Martin, introduced the legislative act to organize the Minnesota Territory. But in 1904 the county’s oldest residents attested that the name referred to Henry Martin, an early settler from Connecticut who ran several businesses during the pre-territory era.
