Nemaha 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.
In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U.S. state. In 1855, Nemaha County was established.
The first railroad in Nemaha County was built in 1866.
On May 30, 1879, the "Irving, Kansas Tornado" passed through Nemaha county. This tornado measured F4 on the Fujita scale, and had a damage path 800 yards (730 m) wide and 100 miles (160 km) long. Eighteen people were killed and sixty were injured in this tornado.
