In 1802, Spain returned most of the land to France while keeping title to about 7,500 square miles. In 1803, most of the land formodern day Kansas was acquired by the United States from France as part of the 828,000 square milesLouisiana Purchase for 2.83cents peracre.
In 1854, theKansas Territory was organized, then in 1861Kansas became the 34thU.S. state. In 1873, the remaining unorganized western part of the state was divided into 22 new counties, includingSheridan County.[3] Sheridan County was then organized in 1880, with the county seat at Kenneth.[4] After it became apparent in 1886, that the railroad line coming to the area would run south of Kenneth to the new town of Hoxie, the residents of Kenneth accepted an offer to get new lots in Hoxie (and move their buildings at no expense), and the county seat transferred to Hoxie. The Lincoln-Colorado railroad line opened through the county in 1888, and formally became part of theUnion Pacific Railroad in the late 1890s.
The population of Sheridan County grew in the early 20th century and peaked in 1930 at 6,038 residents. Since then the population has steadily declined, as part of the generaldepopulation of the Great Plains.
The rail line stayed in operation in Sheridan County until 1998. After flooding east ofPlainville in the1993 floods damaged the line, the railroad concluded it would not be cost effective to rebuild, and the entire line from Plainville toColby was abandoned by 1998.[5][6]
