The book examines the nexus between political and religious thought within the Prussian old conservative milieu. It presents early-nineteenth-century Prussian conservatism as a phenomenon connected to a specific generation of young Prussians. The book introduces the ecclesial-political ‘party of the Evangelische Kirchenzeitung’ (EKZ), a religious party within the Prussian state church, as the origins of Prussia’s conservative party post-1848. It traces the roots of the EKZ party back to the experiences of the Napoleonic Wars (1806-15) and the social movements dominant at that time. 
Additionally, the book analyses this generation’s increasing politicization and presents the German revolution of 1848 and the foundation of Prussia’s first conservative party as the result of a decade-long struggle for a religiously-motivated ideal of church, state, and society. The overall shift from church politics to state politics is key to understanding conservative policy post-1848. Consequently, this book shows how conservatives aimed to maintain Prussia’s character as a Christian and monarchical state, while at the same time adapting to contemporary political and social circumstances. 
Therefore, the book is a must-read for researchers, scholars, and students of Political Science and History interested in a better understanding of the origins and the evolution of Prussian conservatism, as well as the history of political thought.
