Plymouth County was formed on January 15, 1851 and was named for Plymouth, Massachusetts.

During the Great Depression, farmers in the county organized the Farmers Holiday Group, to keep farm products off the market until the desired price was met. A radical group among them abducted Judge Bradley from his court chamber and threatened to hang him in the front of the courthouse. Bradley was freed, but the governor ordered the national guard to Plymouth County and declared a state of emergency, which effectively ended the group.
