The Federalist represents one side of one of the most momentous political debates ever conducted: whether to ratify, or to reject, the newly drafted American constitution. This authoritative new edition presents complete texts for all of the eighty-five Federalist papers, along with the sixteen letters of "Brutus", the unknown New York Antifederalist. Each paper is systematically cross-referenced to the other, and both to the appended Articles of Confederation and U.S. Constitution. Terence Ball's editing skills enhance the accessibility of a classic of political thought in action.
