Franklin 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.
The area was included in a treaty ceding land to the Osage Nation in 1808, and ceded back to the federal government in 1825. After 1825 and prior to 1867, treaties with various Indian nations set off parts of what was later to become Franklin County for the use of Indian tribes removed from their ancestral lands. These tribes included: Ottawa, Chippewa, Sac and Fox, Peoria, and Potawatomi.
In 1854, the Kansas Territory was organized under the provisions of the Kansas-Nebraska Act. In 1855, Franklin County was established as one of the 33 original Kansas Territory counties created by the first Territorial Legislature of 1855. The county was named after Benjamin Franklin. In 1861, Kansas became the 34th U.S. state.
