Peter Iver Kaufman explores how various Christian leaders throughout history have used forms of "political theology" to merge the romance of conquest and empire with hopes for political and religious redemption. His discussion covers such figures as Constantine, Augustine, Charlemagne, Pope Gregory VII, Dante, Zwingli, Calvin, and Cromwell. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
