The Sioux ( /ˈsuː/) are Native American and First Nations people in North America. The term can refer to any ethnic group within the Great Sioux Nation or any of the nation's many language dialects. The Sioux comprise three major divisions based on Siouan dialect and subculture:

Today, the Sioux maintain many separate tribal governments scattered across several reservations, communities, and reserves in the Dakotas, Nebraska, Minnesota, and Montana in the United States; and Manitoba and southern Saskatchewan in Canada.

The name "Sioux" is an abbreviated form of Nadouessioux borrowed into Canadian French from Nadoüessioüak from the early Odawa exonym: naadowesiwag "Sioux".Jean Nicolet recorded the use in 1640. The Proto-Algonquian form *na·towe·wa, meaning "Northern Iroquoian", has reflexes in several daughter languages that refer to a small rattlesnake (massasauga, Sistrurus). This information was interpreted by some that the Odawa borrowing was an insult. However, this Proto-Algonquian term most likely was ultimately derived from a form *-a·towe·, meaning simply "to speak a foreign language". - which would make it similar to the etymology of the Greek "Barbarian". Later this was extended in meaning in some Algonquian languages to refer to the massasauga. Thus, contrary to many accounts, the old Odawa word naadowesiwag did not equate the Sioux with snakes. This is not confirmed though, since usage over the previous decades has led to this term having negative connotations to those tribes to which it refers. This would explain why many tribes have rejected this term as an exonym.

Sitting Bull (Lakota: Tȟatȟáŋka Íyotake in Standard Lakota Orthography, also nicknamed Slon-he or "Slow"; c. 1831 – December 15, 1890) was a Hunkpapa Lakota Sioux holy man who led his people as a tribal chief during years of resistance to United States government policies. Born near the Grand River in Dakota Territory, he was killed by Indian agency police on the Standing Rock Indian Reservation during an attempt to arrest him and prevent him from supporting the Ghost Dance movement.

He had a premonition of defeating the cavalry, which motivated his Native American people to a major victory at the Battle of the Little Bighorn against Lt. Col. George Armstrong Custer and the 7th Cavalry on June 25, 1876. Months after the battle, Sitting Bull and his group left the United States to Wood Mountain, Saskatchewan, where he remained until 1881, at which time he surrendered to U.S. forces. A small remnant of his band under Chief Waŋblí Ǧí decided to stay at Wood Mountain. After his return to the United States, he briefly toured as a performer in Buffalo Bill's Wild West Show, earning $50 a week.
