Historic Itazipcho thiyóšpaye or bands
The Itazipcho (Lakota: – ‘Without Bows’, 'Sans Arcs') are a Native American people constituting a subdivision of the Lakota people, belonging to the old "Saone" group, who formerly inhabited an area in western present-day North Dakota from the Grand River in to the Little Missouri, having south the Sihasapa and north the Hunkpapa. Together with the Miniconjou and Two Kettles (Oóhe Núŋpa, Oóhenuŋpa, Oohenonpa – ‘Two Boiling’ or ‘Two Kettles’) the Itazipcho (Itázipčho, Itazipcola, Hazipco – ‘Those who hunt without bows’) were often referred to as Central Lakota and divided into several bands or thiyóšpaye (Sans Arc, Red Water, Ham Eaters).
The contemporary population lives mostly in west-central South Dakota. Perhaps the most famous Itazipcho chief was No Horn (He Napin Wanica), and, later, Spotted Eagle (Wambli Galeshka) who fought at Little Bighorn.
Currently the Itazipcho descendants live in South Dakota, on the Cheyenne River Indian Reservation (set up in 1889 on a part of the old Grand Sioux Reservation), as members of the Cheyenne River Lakota Oyate, together with the Oohenonpa, Minneconjou and Sihasapa descendants.
