When the Spanish explorer Francisco Vásquez de Coronado visited (1541) the Kansas area in his search for Quivira, a fabled kingdom of riches, the area was occupied by various Native American groups of the Plains descent, notably the Kansa, the Wichita and the Pawnee. Another Spanish explorer, Juan de Oñate, penetrated the region in 1601. A result of Spanish entry into the region was the introduction of the horse, which revolutionized the life of the Native Americans. While not actually exploring the Kansas area, Robert Cavelier, sieur de La Salle, claimed (c.1682) for France all territory drained by the Mississippi River, including Kansas.
French traders and Native Americans had a great deal of contact during most of the 18th cent. By the Treaty of Paris of 1763 ending the French and Indian Wars, France ceded the territory of W Louisiana (including Kansas) to Spain. In 1800, Spain secretly retroceded the territory to France, from whom the United States acquired it in the Louisiana Purchase in 1803. The region was little known, however, and subsequent explorations to include Kansas were the Lewis and Clark expedition (1803–6), the Arkansas River journey of Zebulon M. Pike in 1806, and the scientific expedition of Stephen H. Long in 1819.
Most of the territory that eventually became Kansas was in an area known as the "Great American Desert," considered unsuitable for U.S. settlement because of its apparent barrenness. In the 1830s the region was designated a permanent home for Native Americans, and northern and eastern tribes were relocated there. Forts were constructed for frontier defense and for the protection of the growing trade along the Santa Fe Trail, which crossed Kansas. Fort Leavenworth was established in 1827, Fort Scott in 1842, and Fort Riley in 1853.
Kansas, at this time mainly a region to be crossed on the way to California and Oregon, was organized as a territory in 1854. Its settlement, however, was spurred not so much by natural westward expansion as by the determination of both proslavery and antislavery factions to achieve a majority population in the territory. The struggle between the factions was further complicated by conflict over the location of a transcontinental railroad, with proponents of a central route (rather than a southern route) eager to resolve the slavery issue in the area and promote settlement.
The Kansas-Nebraska Act (1854), an attempted compromise on the extension of slavery, repealed the Missouri Compromise and reopened the issue of extending slavery north of lat. 36°30− by providing for popular sovereignty in Kansas and Nebraska, allowing settlers of territories to decide the matter themselves. Meanwhile, the Emigrant Aid Company was organized in Massachusetts to foster antislavery immigration to Kansas, and proslavery interests in Missouri and throughout the South took counteraction. Towns were established by each faction—Lawrence and Topeka by the free-staters and Leavenworth and Atchison by the proslavery settlers.
Soon all the problems attendant upon organizing a territory for statehood became subsidiary to the single issue of slavery. The first elections in 1854 and 1855 were won by the proslavery group; armed Missourians intimidated voters and election officials and stuffed the ballot boxes. Andrew H. Reeder was appointed the first territorial governor in 1854. The first territorial legislature ousted (1855) all free-state members, secured the removal of Gov. Reeder, established the capital in Lecompton, and adopted proslavery statutes. In retaliation the abolitionists set up a rival government at Topeka in Oct., 1855.
Violence soon came to the territory. The murder of a free-state man in Nov., 1855, led to the so-called Wakarusa War, a bloodless series of encounters along the Wakarusa River. The intervention of the new governor, Wilson Shannon, kept proslavery men from attacking Lawrence. However, civil war ultimately turned the territory into "bleeding Kansas." On May 21, 1856, proslavery groups and armed Missourians known as "Border Ruffians" raided Lawrence. A few days later a band led by the abolitionist crusader John Brown murdered five proslavery men in the Pottawatamie massacre. Guerrilla warfare between free-state men called Jayhawkers and proslavery bands—both sides abetted by desperadoes and opportunists—terrorized the land. After a new governor, John W. Geary, persuaded a large group of "Border Ruffians" to return to Missouri, the violence subsided.
The Lecompton legislature met in 1857 to make preparations for convening a constitutional convention. Gov. Geary resigned after it became clear that free elections would not be held to approve a new constitution. Robert J. Walker was appointed governor, and a convention held at Lecompton drafted a constitution. Only that part of the resulting proslavery constitution dealing with slavery was submitted to the electorate, and the question was drafted to favor the proslavery group. Free-state men refused to participate in the election with the result that the constitution was overwhelmingly approved.
Despite the dubious validity of the Lecompton constitution, President James Buchanan recommended (1858) that Congress accept it and approve statehood for the territory. Instead, Congress returned it for another territorial vote. The proslavery group boycotted the election, and the constitution was rejected. Lawrence became de facto capital of the troubled territory until after the Wyandotte constitution (framed in 1859 and totally forbidding slavery) was accepted by Congress. The Kansas conflict and the question of statehood for the territory became a national issue and figured in the 1860 Republican party platform.
Kansas became a state in 1861, with the capital at Topeka. Charles Robinson was the first governor and James H. Lane, an active free-stater during the 1850s, one of the U.S. Senators. In the Civil War, Kansas fought with the North and suffered the highest rate of fatal casualties of any state in the Union. Confederate William C. Quantrill and his guerrilla band burned Lawrence in 1863.
With peace came the development of the prairie lands. The construction of railroads made cow towns such as Abilene and Dodge City, with their cowboys, saloons, and frontier marshals, the shipping point for large herds of cattle driven overland from Texas. The buffalo herds disappeared (some buffalo still roam in state parks and game preserves), and cattle took their place. Pioneer homesteaders, adjusting to life on the timberless prairie and living in sod houses, suffered privation. In 1874, Mennonite emigrants from Russia brought the Turkey Red variety of winter wheat to Kansas. This wheat was instrumental in making Kansas the Wheat State as winter wheat replaced spring wheat on an ever-increasing scale. Corn, too, soon became a major cash crop.
Agricultural production was periodically disrupted by national depressions and natural disasters. Repeated and prolonged droughts accompanied by dust storms, occasional grasshopper invasions, and floods all caused severe economic dislocation. Mortgages often weighed heavily on farmers, and discontent was expressed in farmer support of radical farm organizations and third-party movements, such as the Granger movement, Greenback party, and Populist party. Tax relief, better regulation of interest rates, and curbs on the power of railroads were sought by these organizations. Twice in the 1890s, Populist-Democrats were elected to the governorship.
As conditions improved, Kansas returned largely to its allegiance to the Republican party and gained a reputation as a conservative stronghold with a bent for moral reform, indicated in the state's strong support of prohibition; laws against the sale of liquor remained on the books in Kansas from 1880 to 1949. Over the years the use of improved agricultural methods and machines increased crop yield. Irrigation proved practicable in some areas, and winter wheat and alfalfa could be cultivated in dry regions.
Wheat production greatly expanded during World War I, but the end of the war brought financial difficulties. During the 1920s and 30s, Kansas was faced with labor unrest and the economic hardships of the depression. As part of the Dust Bowl, Kansas sustained serious land erosion during the long drought of the 1930s. Erosion led to the implementation of conservation and reclamation projects, particularly in the northern and western parts of the state. In 1924 an effort of the Ku Klux Klan to gain political control was fought by William Allen White, editor of the Emporia Gazette, who supported many liberal causes. Alfred M. Landon, elected governor in 1932, was one of the few Republican candidates in the country to win election in the midst of the sweeping Democratic victory that year. He was nominated as the Republican presidential candidate in 1936.
During World War II agriculture thrived and industry expanded rapidly. The food-processing industry grew substantially, the cement industry enjoyed a major revival, and the aircraft industry boomed. After the war agricultural prosperity once again declined when the state was hit by a severe drought and grasshopper invasion in 1948. Prosperity returned briefly during the Korean War, but afterward farm surpluses and insufficient world markets combined to make the state's tremendous agricultural ability part of the national "farm problem."
Kansas has become increasingly industrialized and urbanized, and industrial production has surpassed farm production in economic importance. Flood damage in the state, especially after a major flood in 1951, spurred the construction of dams (such as the Tuttle Creek, Milford, and Wilson dams) on major Kansas rivers, and their reservoirs have vastly increased water recreational facilities for Kansans. Since the 1970s, Kansas has become increasingly more urban and suburban. Accordingly, the economy has shifted its emphasis to finance and service industries located in and around the major urban centers.
