This volume brings together a set of papers by international scholars, distinguished in their own right, in honor of James Brundage. Each contribution corresponds to an important focus of Brundage's own work. The connection between the development of medieval legal thought and constitutional ideas is the theme that marks the first section, while the second centers on the growth of the legal profession. The following papers explore the intersection of law and marriage and finally the influence of legal thinking on the crusading movement.
