Key Topics served as a nexus between research groups in different research areas. We took into account the need for intensive communication between different research groups by organizing a series of those Key Topics that fostered interaction throughout the cluster: each Key Topic was organized and led by a particular research group. This “lead project/group” was responsible for fostering exchanges between the different research areas and synthesizing the different concepts applied to one and the same historical phenomenon as seen from quite different disciplinary perspectives. Some of these themes were organized by junior research groups.
