Kansas

Kansas (/ˈkænzəs/ ^ⓘ KAN-zəss) is a landlocked state in the Midwestern region of the United States. It borders Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, in turn named after the Kansa people. Its capital is Topeka, and its most populous city is Wichita; however, the largest urban area is the bi-state Kansas City metropolitan area split between Kansas and Missouri.

For thousands of years, what is now known as Kansas was home to numerous and diverse Indigenous tribes. The first settlement of non-indigenous people in Kansas occurred in 1827 at Fort Leavenworth. The pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery debate. When it was officially opened to settlement by the U.S. government in 1854 with the Kansas–Nebraska Act, conflict between abolitionist Free-Staters from New England and pro-slavery settlers from neighboring Missouri broke out over the question of whether Kansas would become a free state or a slave state, in a period known as Bleeding Kansas. On January 29, 1861, Kansas entered the Union as a free state, hence the unofficial nickname "The Free State". Passage of the Homestead Acts in 1862 brought a further influx of settlers, and the booming cattle trade of the 1870s attracted some of the Wild West's most iconic figures to western Kansas.

As of 2015, Kansas was among the most productive agricultural states, producing high yields of wheat, corn, sorghum, and soybeans. In addition to its traditional strength in agriculture, Kansas possesses an extensive aerospace industry. Kansas, which has an area of 82,278 square miles (213,100 square kilometers) is the 15th-largest state by area, the 36th most-populous of the 50 states, with a population of 2,940,865 according to the 2020 census, and the 10th least densely populated. Residents of Kansas are called Kansans. Mount Sunflower is Kansas's highest point at 4,039 feet (1,231 meters).

Kansas is generally considered to be the geographic center of the contiguous United States, with Lebanon being approximately the center.

The name Kansas derives from the Algonquian term Akansa, referring to the Quapaw people. These were a Dhegiha Siouan-speaking people who settled in Arkansas around the 13th century. The stem -kansa is named after the Kaw people, also known as the Kansa, a federally recognized Native American tribe. The tribe's name (natively kką:ze) is often said to mean "people of the (south) wind", although this was probably not the term's original meaning.

Before European colonization, Kansas was occupied by the Caddoan Wichita and later the Siouan Kaw people. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison. The first European to set foot in present-day Kansas was the Spanish conquistador Francisco Vázquez de Coronado, who explored the area in 1541.

Between 1763 and 1803, the territory of Kansas was integrated into Spanish Louisiana. During that period, Governor Luis de Unzaga 'le Conciliateur' promoted expeditions and good relations with the Amerindians. Explorer Antoine de Marigny and others continued trading across the Kansas River, especially at its confluence with the Missouri River, tributaries of the Mississippi River.

In 1803, most of modern Kansas was acquired by the United States as part of the Louisiana Purchase. Southwest Kansas, however, was still a part of Spain, Mexico, and the Republic of Texas until the conclusion of the Mexican–American War in 1848, when these lands were ceded to the United States. From 1812 to 1821, Kansas was part of the Missouri Territory. The Santa Fe Trail traversed Kansas from 1821 to 1880, transporting manufactured goods from Missouri and silver and furs from Santa Fe, New Mexico. Wagon ruts from the trail are still visible in the prairie today.
