About this book:

*Faith and Power: Religion's Role in European Politics* examines the enduring influence of Christianity on European governance from late antiquity to the contemporary era. The book begins by tracing the transformation of the Roman Empire into Christendom, highlighting how the fusion of imperial authority and church doctrine under figures like Constantine and Theodosius I created a template for medieval political legitimacy. It explores the tension between "throne and altar" through the Investiture Struggle and the development of canon law, which provided an administrative and legal framework that shaped the architecture of modern statecraft and judicial procedure.

The narrative shifts to the fragmentation of Western religious unity during the Reformation. It analyzes how Martin Luther’s "two kingdoms" doctrine and John Calvin’s model of moral discipline in Geneva transformed theology into a tool for state-building and social control. This period of "confessionalization" saw European rulers use religious identity to consolidate territorial sovereignty, a process that eventually culminated in the catastrophic Thirty Years’ War. The resulting Peace of Westphalia in 1648 is presented as a pivotal moment that established the sovereign state system, successfully re-containing religious conflict by prioritizing *raison d'état* over confessional solidarity.

The book then follows the trajectory of religion through the Enlightenment and the French Revolution, illustrating how the rise of secular rationalism and republicanism stripped churches of their traditional land and legal privileges. It traces the 19th-century emergence of Social Catholicism and Christian Democracy as the Church’s response to industrialization and liberalism, followed by the harrowing challenges posed by 20th-century totalitarianism. While communism sought the eradication of faith, fascist regimes often attempted to co-opt it, forcing churches into difficult positions of collaboration, quiet endurance, or principled resistance.

In its final chapters, the text addresses the post-war landscape, from the reforms of Vatican II to the institutionalization of European integration. It concludes with a modern analysis of secularization and pluralism, noting that while institutional religious practice has declined in Western Europe, faith remains a potent political force. The arrival of Islam as a significant European religion and the rise of right-wing populists who invoke "Christian heritage" as a civilizational boundary demonstrate that the historical dialogue between faith and power continues to be a central, contested feature of European identity and governance.

What You'll Find Inside:

• How Christianity transformed late Roman governance through imperial patronage, ecclesiastical courts, and the migration of spiritual authority from emperor to pope
• The Reformation's creation of confessional politics where rulers gained authority to determine their subjects' religion, reshaping European state-building
• How confessionalization synchronized catechisms, courts, and coercion to forge disciplined communities and bureaucratic capacities in early modern states
• The Enlightenment's secularizing impact that reallocated spiritual authority into rights-based discourse while enabling state control of churches through concordats and cultural campaigns
• Contemporary Europe's religious pluralism challenges from migration, Islam, and populist movements that renew debates about identity, law, and neutrality

Who's It For:

This book is intended for students, scholars, and educated readers interested in European history, religious studies, and political science. It will particularly benefit those seeking to understand the historical foundations of contemporary European debates about secularism, religious identity, migration, and the relationship between faith and state power. Readers will gain insight into how theological developments and social realities have co-produced European governance patterns over two millennia, from the late antique transformation of the Roman Empire to modern challenges of pluralism and populism.
