The Oglala Lakota or Oglala Sioux (meaning "to scatter one's own" in Lakota language) are one of the seven subtribes of the Lakota people; along with the Nakota and Dakota, they make up the Great Sioux Nation. A majority of the Oglala live on the Pine Ridge Indian Reservation in South Dakota, the eighth-largest Native American reservation in the United States. The Oglala are a federally recognized tribe whose official title is the Oglala Sioux Tribe of the Pine Ridge Reservation. The Oglala Lakota, along with the six other groups of Lakota, had separated from each other by the early 19th century. By 1830, the Oglala had around 3,000 members. In the 1820s and 1830s, the Oglala, along with the Brule, another Lakota band, and three other Sioux bands, formed the Sioux Alliance. This Alliance attacked surrounding tribes for territorial and hunting reasons. Surrounded By the Enemy performed during a European tour of Buffalo Bill's Wild West Show in London.
