Kansas is a 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, MO–KS metropolitan area. For thousands of years, what is now Kansas was home to numerous and diverse Indigenous tribes.
