History
Early history
For 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 via the Third Treaty of San Ildefonso, although the former country kept 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.
19th century
In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U.S. state. In 1855, Douglas County was established. Douglas County was opened for settlement on May 15, 1854, and was named for Stephen A. Douglas, a senator from Illinois. The county was practically at the center of the Bleeding Kansas years as leaders in Lecompton (the territorial capital) wanted Kansas to be a slave state, whereas leaders in Lawrence wanted Kansas to be a free state. The pro- and anti-slavery settlers held great animosity towards one another, leading to many events, such as the drafting of the Lecompton Constitution (which would have admitted Kansas into the Union as a slave state), the Wakarusa War (1855), the Sack of Lawrence (1856), Battle of Black Jack (1856), and the Lawrence Massacre (1863).
The first railroad in Douglas County, the Kansas Pacific, was built through that territory in 1864.
