Exploring Doniphan County's Past
How Doniphan County Began
For thousands of years, the Great Plains of North America were home to nomadic Native American tribes. In the 16th to 18th centuries, France claimed large areas of North America. In 1762, after a war, France secretly gave this land to Spain.
Later, in 1802, Spain returned most of the land to France. Then, in 1803, the United States bought a huge amount of land from France. This was part of the Louisiana Purchase. Most of what is now Kansas was included in this deal.
Becoming a County
The Kansas Territory was set up in 1854. Kansas officially became the 34th U.S. state in 1861. Doniphan County was created on August 25, 1855. It was named after Colonel Alexander William Doniphan. He was a U.S. cavalry leader who played an important role in the Mexican–American War.
Geography and Nature
Doniphan County is in the very northeast corner of Kansas. It shares borders with Nebraska to the north and Missouri to the east. The county covers about 398 square miles. Most of this is land (393 square miles), and a small part is water (4.9 square miles). It is one of the smallest counties in Kansas.
Rivers and Water Sources
The Missouri River forms the border on the north and east sides of the county. This river is important for shipping goods. It also provides a lot of water for the eastern part of the county. Towns further inland, like Troy and Highland, get their water from underground wells. The Wolf River flows through the western parts of the county.
