Bancroft's life work, the pioneering, monumental, multi-volume History of the United States, from the Discovery of the American Continent, was notable for its Democratic, rather than Federalist, point of view. This volume covers, among many other events, Columbus's discovery of the New World, a history of the slave trade, the Icelandic voyages, and the Restoration of the Stuarts, as well as all issues of colonization and religion.
