Kansas is a Midwestern state in the central region of the United States of America, an area often referred to as the American "Heartland". It is named after the Kansas River which flows through it, which in turn was named after the Kansa tribe, who inhabited the area.
The tribe's name is often said to mean "people of the wind" or "people of
the south wind", although this was probably not the term's original meaning.
Residents of Kansas are called "Kansans".
Historically, the area was home to large numbers of nomadic Native Americans that hunted bison. It was first settled by European Americans in the 1830s, but the pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery issue. When officially opened to settlement by the U.S. government in 1854, abolitionist Free-Staters from New England and pro-slavery settlers from neighboring Missouri rushed to the territory to determine if Kansas would become a free state or a slave state.
Thus, the area was a hotbed of violence and chaos in its early days as these forces collided, and was known as Bleeding Kansas. The abolitionists eventually prevailed and on January 29, 1861, Kansas entered the Union as a free state. After the Civil War, the population of Kansas exploded when waves of immigrants turned the prairie into productive farmland. Today, Kansas is one of the most productive agricultural states, producing many crops, and leading the nation in wheat and sunflower production most years.
