History

Early history

For millennia, the Great Plains of North America was inhabited by nomadic Native Americans. Numerous tribes lived on the Great Plains including the: Arapaho, Cheyenne, Comanche, Sioux, Ute, Otoe, Kansa, Kiowa, Osage, Omaha, Ponca, Pawnee, and Wichita. These tribes were sustained by a seemingly inexhaustible supply of buffalo that then numbered in the tens of millions.

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 1857, Washington County was established. The Oregon-California Trail, the Overland Stage Line, and the Pony Express all ran through Washington County. The Hollenberg Way Station opened in 1857 and operated until 1872 in the northeast corner of the county.

21st century

In 2010, the Keystone-Cushing Pipeline (Phase II) was constructed north to south through Washington County, with much concern over tax exemption and environmental issues when a leak occurs. The pipeline was shutdown on December 7, 2022, after a leak was detected near the community of Washington. It reopened on December 29, 2022.
