Book excerpt: This book explores the concept of religious Enlightenment in the Nordic countries during the long eighteenth century. It argues that Lutheran confessional culture became intertwined with Enlightenment ideas and practices in this European region. In the book’s three parts, specialist historians explore themes central to students of the early modern era – historical writing, material culture, ecclesiastical and legal reform, censorship, cameralism and innovative medical practices. It offers a timely reconsideration of a complex period in European history from a northern perspective.
