Factional Struggles explores the dynamics of conflicts among ruling elites within cities, dynastic courts, rural areas and regional noble lineages during the early modern period. Building on case studies from France, Italy, the Empire and the Swiss Confederation, the essays collected by Mathieu Caesar in this volume highlight how factions were formed and how they shaped political society from the late Middle Ages. The authors have especially focused on how political and religious ideologies contributed to the formation of partisanship, the role of propaganda, and the significance and strategies of factional leaders. The volume shows how factions, despite the generally negative view of them held by theologians and jurists, were in practice accepted and used as political tools.
