History

Early history

See also: History of Kansas

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.

19th century

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, Leavenworth County was established, and is among the first 33 counties, which were formed by the first territorial government. It was named, as was its county seat, after Henry Leavenworth, an officer in the War of 1812. ^[5]

Leavenworth County had the first Kansas State University extension agent in the State.
