The constitution that establishes the institutional framework for American national government makes no mention of political parties. Yet for over two centuries, political parties have competed in encouraging, organizing, and directing political activity in the United States. This volume compiles entries of concepts, terms, labels, and individuals central to identifying and comprehending these key roles political parties have played in American political life.

The second edition of Historical Dictionary of United States Political Parties addresses the historical development, organization, operation, and leadership of the parties, as well as their broader environment. This is done through a chronology, an introductory essay, appendixes, a bibliography, and over 800 cross-referenced dictionary entries addressing individuals, institutions, and terms.
