The scholarly book "Samtherrschaft - Kondominium - Gemeinderschaft" offers a comprehensive analysis of the samtherrschaften and kondominaten in the Holy Roman Empire, based on a conference that took place in October 2023 at the Heidelberg Academy of Sciences. The volume highlights the political and legal frameworks that shaped life in medieval and early modern cities. In contrast to previous regional approaches, it provides a comparative perspective on the effects of shared city governance on the cities and their inhabitants. Through concrete examples, the complexity of shared governance structures and their influence on urban society is examined in detail. Contributions from renowned scholars provide valuable insights into the topic and enhance the understanding of the dynamics of power relations in this historical period.
