Written by Dee Brown and published in 1971, Bury My Heart at Wounded Knee was an inspiration to the emerging American Indian Movement and to the student protesters of the 1960s and early 1970s. It also reestablished Wounded Knee as a symbol of what the westward expansion of America cost its native population in blood and tears. Although the book begins as far back as Columbus, it concentrates on the period from 1860 to 1890. For his material, Brown drew on the American West were written from the white man's perspective, so he sought to reconstruct the conquest from the oral histories recounted in these documents, using the Indians' won words as much as possible.
