Linn County, Kansas: History
=== Early history ===
For many millennia, the Great Plains of North America was inhabited by nomadic Native Americans. From the 16th century to 18th century, the Kingdom of France claimed ownership of large parts of North America. In 1762, after the French and Indian War, France secretly ceded New France to Spain, per the Treaty of Fontainebleau.
In 1802, Spain returned most of the land to France, but keeping title to about 7,500 square miles. In 1803, most of the land for modern day Kansas was acquired by the United States from France as part of the 828,000 square mile Louisiana Purchase for 2.83 cents per acre.
Explorers in the early 19th century came across abandoned mining sites along a creek south of the Marais des Cygnes river. The background of these early miners remains a mystery; but it inspired early residents of the region to name this waterway "Mine Creek."
