Plymouth County History
Plymouth County’s early development grew from frontier settlements established in the mid-1850s, eventually shaping a community known for its strong agricultural roots. Formed in 1851, the county first located its courthouse in Melbourne before relocating the seat to Le Mars in 1872. A new stone courthouse was completed in 1900, standing as a lasting landmark. Notable historical events include the 1930s Farmers Holiday movement, during which tensions over farm prices led to statewide intervention. Additional historical details are available on Wikipedia.
