Platte County, Missouri has a rich and diverse history that dates back to the early 19th century. The area was inhabited by various Native American tribes, including the Kansas, Osage, and Missouri Indians, before European settlers arrived. Trading became an important activity along the Missouri River, which runs through the county, and in 1838, Parkville was established as one of the first settlements in the area.

During the mid-1800s, Platte County experienced significant growth due to the California Gold Rush and the establishment of the Platte Purchase. This brought a large number of settlers and migrants passing through the area on their way west. Platte County became an important hub for trading and transportation, with steamboats serving as a vital means of transport on the Missouri River.

The county played a significant role in the American Civil War.

The end of the war brought an end to this period of conflict and allowed for the county's recovery and growth.
