Photo taken December 1907 of a party of Brule Sioux Indians on horseback, many wearing war bonnets, re-enacting a raid across the plains against their enemies. The image, entitled "Brule War Party", was captured by Edward S Curtis (1868 - 1952) as part of his project "The North American Indian". Curtis took thousands of pictures of over 80 Indian tribes to be published in 20 volumes from 1907 - 1930 with the aim of documenting as much Native American Indian traditional life as possible before that way of life disappeared. Much of the material he obtained is the only recorded history of those times. The Brule are one of the branches or "sub-tribes" of the Lakota Sioux occupying lands in North and South Dakota.
