The Reformation not only changed theology and the church, but set in motion a fundamental transformation, which encompassed every aspect of society. Thus, Protestantism had an enduring influence on social structures, patterns of perception, normative ideas, scientific concepts, scopes for artistic expression and cultural identities. The announced proceedings document the international and interdisciplinary congress Cultural Impacts of the Reformation held in August 2017 by the universities of Halle-Wittenberg, Jena and Leipzig at the LEUCOREA Foundation in Lutherstadt Wittenberg. The contributions - amongst others by Udo Strater, Charlotte Methuen, Martin Heckel, Herman Selderhuis, Rudolf von Sinner, Daniel Jeyaraj and Jochen Horisch - show precisely both the ways the Protestant confessional milieus have been influential for 500 years and how they themselves have reacted to cultural challenges.
