Butler 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 1848, after the Mexican–American War, the Treaty of Guadalupe Hidalgo with Spain brought into the United States all or part of land for ten future states, including southwest Kansas. In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U.S. state.
In 1855, Butler County was founded. It was named in honor of a U.S. senator from South Carolina, Andrew Butler (1796-1857), who was one of the authors of the Kansas-Nebraska Act of 1854 and a strong advocate of Kansas becoming a slave state.
In 1877, the Florence, El Dorado, and Walnut Valley Railroad Company built a branch line from Florence to El Dorado, in 1881 it was extended to Douglass, and later to Arkansas City. The line was leased and operated by the Atchison, Topeka and Santa Fe Railway. The line from Florence to El Dorado was abandoned in 1942. The original branch line connected Florence, Burns, De Graff, El Dorado, Augusta, Douglass, Rock, Akron, Winfield, Arkansas City.
In 1887, the Chicago, Kansas and Nebraska Railway built a branch line north–south from Herington to Caldwell. This branch line connected Herington, Lost Springs, Lincolnville, Antelope, Marion, Aulne, Peabody, Elbing, Whitewater, Furley, Kechi, Wichita, Peck, Corbin, Wellington, Caldwell. By 1893, this branch line was incrementally built to Fort Worth, Texas. This line is called the "OKT". The Chicago, Kansas and Nebraska Railway was foreclosed in 1891 and was taken over by Chicago, Rock Island and Pacific Railway, which shut down in 1980 and reorganized as Oklahoma, Kansas and Texas Railroad, merged in 1988 with Missouri Pacific Railroad, and finally merged in 1997 with Union Pacific Railroad. Most locals still refer to this railroad as the "Rock Island".
In 2010, the Keystone-Cushing Pipeline (Phase II) was constructed north to south through Butler County (near Potwin, Towanda, Augusta, Douglass), with much controversy over tax exemption and environmental concerns (if a leak ever occurs). A pumping station named Burns was built two miles north of Potwin, and new power lines were built from a high-voltage line 0.3 mile east of De Graff.
In an unusual technical glitch, a farmstead approximately four miles northeast of Potwin became the default site of 600 million IP addresses (due to their lack of fine granularity) when the Massachusetts-based digital mapping company MaxMind changed the putative geographic center of the contiguous United States from 39.8333333,-98.585522 to 38.0000,-97.0000.
