Bury My Heart at Wounded Knee

This book by Dee Brown was hugely influential, very widely read, and repeatedly reprinted. It was a watershed in opening the eyes of "the Average American" to another way of looking at the Indian Wars, Manifest Destiny, and the Reservation system. It continues to be well regarded and heavily referenced.

Certainly it expanded awareness of N.A. points of view and, by presenting them as heroes and underdogs, it moved people toward sympathy and a desire to empathize with the Indians.

Between 1971 and 1975 there were 39 printings. Think of the impact that many printings would have.
