Winner of both the Pulitzer Prize and Bancroft Prize for History, Great River was hailed as a literary masterpiece and enduring classic when it first appeared in 1954. It is an epic history of four civilizations—Native American, Spanish, Mexican, and Anglo-American—that people the Southwest through ten centuries. With the skill of a novelist, the veracity of a scholar, and the love of a long-time resident, Paul Horgan describes the Rio Grande, its role in human history, and the overlapping cultures that have grown up alongside it or entered into conflict over the land it traverses. Now in its fourth revised edition, Great River remains a monumental part of American historical writing.
