In 1847, Protestant missionary Marcus Whitman was killed after a disastrous eleven-year effort to evangelize the indigenous peoples of the Pacific Northwest. By 1897, Whitman was a national hero, celebrated in textbooks, monuments, and historical scholarship as the "Savior of Oregon." But his fame was based on a tall tale--one that was about to be exposed.

Sarah Koenig traces the rise and fall of Protestant missionary Marcus Whitman's legend, revealing two patterns in the development of American history. On the one hand is providential history, marked by the conviction that God is an active agent in human history and that historical work can reveal patterns of divine will. On the other hand is objective history, which arose from the efforts of Catholics and other racial and religious outsiders to resist providentialists' pejorative descriptions of non-Protestants and nonwhites. Koenig examines how these competing visions continue to shape understandings of the American past and the nature of historical truth.
