Kansas is a U.S. state in the Midwestern United States. Its capital is Topeka and its largest city is Wichita, with its most populated county being Johnson County. Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribe's name is often said to mean "people of the wind" although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. 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.
