The long nineteenth century was marked by social, economic, and political upheavals in Europe. The Jewish society also witnessed a modernizing change, which ultimately led to pluralization within the religious world.Subsequent to the Haskalah, Jewish Enlightenment, and in a complex reciprocal relationship with the emerging science of Judaism (Wissenschaft des Judentums), the Jewish reformers implemented progressive changes within the Jewish liturgy which are also reflected in the architecture of Jewish sacral buildings. Starting with the Jakobstempel in Seesen, this volume "Reform Judaism and Architecture" illuminates different aspects of Jewish Reform architecture in overviews and case studies.
