This book is a new edition of Mack P. Holt's classic study of the French religious wars of the sixteenth and seventeenth centuries. Drawing on the scholarship of social and cultural historians of the Reformation, it shows how religion infused both politics and the socio-economic tensions of the period to produce a long extended civil war. Professor Holt integrates court politics and the political theory of the elites with the religious experiences of the popular classes, offering a fresh perspective on the wars and on why the French were willing to kill their neighbors in the name of religion.
