History of Osage County
Early Times
For thousands of years, the Great Plains of North America were home to nomadic Native Americans. These groups moved around to hunt and gather food.
From the 1500s to the 1700s, France claimed a lot of land in North America. This included parts of what is now Kansas. In 1762, after a big war, France secretly gave this land to Spain. This was part of a deal called the Treaty of Fontainebleau.
The 1800s
In 1802, Spain gave most of the land back to France. Then, in 1803, the United States bought a huge area from France. This was called the Louisiana Purchase. Most of modern-day Kansas was part of this purchase. It was a very big deal for the United States.
In 1854, the Kansas Territory was created. This was a step towards Kansas becoming a state. Finally, in 1861, Kansas officially became the 34th U.S. state. Osage County was officially formed in 1859, just before Kansas became a state.
