Putnam County is a county in north central Missouri. At the 2020 census, the population was 4,681.[1] Its county seat is Unionville.[2] The county was organized February 28, 1845, and named for Israel Putnam, a hero in the French and Indian War and a general in the American Revolutionary War.[3]
Putnam County was established February 28, 1845, from parts of Adair and Sullivan counties. The following year a portion of Putnam was removed to form Dodge County. Both Putnam and Dodge extended nearly nine miles further north until an 1851 ruling by the Supreme Court on a border dispute with Iowa assigned the contested land to Iowa. Both counties were left with less than the statutory minimum area for a county as set by the state legislature, so Dodge County was dissolved and its area added to Putnam.[4]
In its early years, the county seat changed frequently, often with contentious debate. Putnamville, Bryant Station (both no longer in existence), and Hartford all served until a central location called Harmony, later renamed Unionville, was chosen.[5]
In the 1860 U.S. Census Putnam County had 9,240 residents, with eighteen sawmills and three flour mills.[6] Coal had been an abundant since its earliest settlement. Following the arrival of the Burlington & Southwestern Railway in 1873, coal mining became a major industry, especially in the east of the county. At one time three railroads crossed Putnam county: the Chicago, Milwaukee and St. Paul; the Chicago, Burlington and Quincy; and the Iowa and St. Louis.[7] Putnam County lost over two-thirds of its population between the years 1900 and 2000 (see census data below), when the United States changed from a rural to an urban country.
