Native America, Discovered and Conquered takes a fresh look at American history through the lens of the Doctrine of Discovery-the legal basis that Europeans and Americans used to lay claim to the land of the indigenous peoples they discovered. Robert J. Miller illustrates how the American colonies used the Doctrine of Discovery against the Indian nations from 1606 forward. Thomas Jefferson used the doctrine to exert American authority in the Louisiana Territory, to win the Pacific Northwest from European rivals, and to conquer the Indian nations. In the broader sense, these efforts began with the Founding Fathers and with Thomas Jefferson's Corps of Discovery, and eventually the Doctrine of Discovery became part of American law, as it still is today. Miller shows how Manifest Destiny grew directly out of the legal elements and policies of the Doctrine of Discovery and how Native peoples, whose rights stood in the way of this destiny, were discovered and then conquered. Miller's analysis of the principles of discovery brings a new perspective and valuable insights to the study of Jefferson, Lewis and Clark, the Louisiana Purchase, the Pacific Northwest, American expansionism, and U.S. Indian policy. This Bison Books edition includes a new afterword by the author.
