Kansas Territory
From June 4, 1812 until August 10, 1821 the area that would become Kansas Territory 33 years later was part of the Missouri Territory. When Missouri was granted statehood in 1821 the area became unorganized territory and contained little to no permanent white settlement with the exception of Fort Leavenworth. The Fort was established in 1827 by Henry Leavenworth with the 3rd U.S Infantry from St. Louis, Missouri; it is the first permanent European settlement in Kansas. The fort was established as the westernmost outpost of the American military to protect trade along the Santa Fe Trail from Native Americans. The trade came from the East, by land using the Boone's Lick Road, or by water via the Missouri River. This area, called the Boonslick, was located due east in west-central Missouri and was settled by Upland Southerners from Virginia, Kentucky, and Tennessee as early as 1812. It's slave-holding population would contrast with settlers from New England who would eventually arrive in the 1850s. 
The land that would become Kansas Territory was considered to be infertile by 19th century American pioneers. It was called the Great American Desert, for it lacked trees and was dryer than land eastward. Technically, it was part of the vast grasslands that make up the North American Great Plains and supported giant herds of American bison. After the invention of the steel plow and more sophisticated irrigation methods the thick prairie soil would be broken for agriculture. By the 1850s immigration pressure was increasing and organization into a Territory was desired.
History of Kansas
Congress began the process of creating Kansas Territory in 1852. That year, petitions were presented at the first session of the Thirty-second Congress for a territorial organization of the region lying west of Missouri and Iowa. No action was at that time taken. However, during the next session, on December 13, 1852, a Representative from Missouri submitted to the House a bill organizing the Territory of Platte: all the tract lying west of Iowa and Missouri, and extending west to the Rocky Mountains. The bill was referred to the United States House Committee on Territories, and passed by the full U.S. House of Representatives on February 10, 1853. However, Southern Senators stalled the progression of the bill in the Senate, while the implications of the bill on slavery and the Missouri Compromise were debated. Heated debate over the bill and other competing proposals would continue for a year, before eventually resulting in the Kansas–Nebraska Act, which became law on May 30, 1854, establishing the Nebraska Territory and Kansas Territory.
