Indigenous peoples, including Omaha, Missouria, Ponca, Pawnee, Otoe, and various branches of the Lakota (Sioux) tribes, lived in the region for thousands of years before European exploration. The state is crossed by many historic trails, including that of the Lewis and Clark Expedition.

Nebraska's area is just over 77,220 square miles (200,000 km2) with a population of over 1.9 million. Its capital is Lincoln, and its largest city is Omaha, which is on the Missouri River. Nebraska was admitted into the United States in 1867, two years after the end of the American Civil War. The Nebraska Legislature is unlike any other American legislature in that it is unicameral, and its members are elected without any official reference to political party affiliation.
