After the introduction of a church order, urban Reformation is usually considered to be completed. Using the example of the autonomous territorial city of Brunswick, Malte de Vries demonstrates, that the “Reformation” was followed by decades of consolidation – the “Implementation”. In order to show this post-Reformation process, a variety of different aspects will be examined: The role of the magistrate and the church institutions aswell as the handling of marriages, the education- or the welfare system. By doing that, the study points out, that the ideal state, demanded in the lutheran church orders, required decades until it was actually realised.
