Civic Humanism has been one of the most influential concepts in the history of ideas ever since the pioneering work of Hans Baron and J. G. A. Pocock. This book reassesses Renaissance republican thinkers in relation to the medieval and early modern traditions of political thought and proposes new understandings of the evolution of important republican concepts. The distinguished team of American and European political theorists and historians together contribute a distinctive and significant addition to the study of republican political ideology.
