What the paper says

Itinerant rule, rule exercised through traveling, was a common yet insufficiently researched, premodern form of governance. Studying the determinants of ruler itineraries in the Holy Roman Empire, AD 919–1519, we argue that rulers' visits targeted “marginal” elites. Powerful rulers could count on family members and thus targeted unrelated local elites. Weak emperors had to monitor their less loyal relatives and left unrelated nobles unvisited. We reconstruct emperors' itineraries from 72,665 dated and geolocated documents and measure territorial control by their relatives. Exploiting the weakening of imperial power through the Great Interregnum (1250–1273), we find that strong, pre‐1250 emperors frequented areas controlled by their relatives relatively less. In contrast, family control increased visits post‐1273. Causal identification rests on the discontinuous reduction of emperors' power through the Great Interregnum and differences in family relations between subsequent emperors. The results show strategic itinerant rule as an important but understudied form of governance.
