History

edit

The county was established by two acts of the Minnesota state legislature, dated March 6, 1868, and March 2, 1869. The county seat was designated as Marshall. The county was named for Nathaniel Lyon, an Army officer who served in the Dakota and Minnesota territories before being killed in the Civil War in 1861. He had achieved the rank of general by his death.[3][4] The county was much larger until an act passed on March 6, 1873, made the western 43% the new Lincoln County.
