Putnam County is a county located in North Central Missouri. Based on the 2010 census, the population was 4,979. Its county seat is
Unionville. 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.
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 of Dodge County. Both Putnam and Dodge extended nearly nine miles further north until a 18561 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.
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
Named for Israel Putnam, a Revolutionary War general.
