The other side of this story, namely the oppression and exploitation of Indian nations and their lands, was at first suppressed, since in this case as in so many historical encounters, the history books are written by the victors, while the victims are left without a voice. Very few scholars took a serious interest in Indian culture and religion, and those who did remain largely confined to academic circles. An exception to this was the work of John Neihart, who realized the historic importance of recollections that were held by Indian peoples. He noted down the life and times of an Indian called Black Elk who was directly involved in some of the most important battles in American history, including the killing of Crazy Horse and the Battle of Wounded Knee. The book was published in English in 1930 but only reached a wider audience in the 1960s and it immediately changed the perspective that ordinary Americans had on their recent history.
