DP18085 Feudal Political Economy
The political economy of medieval Europe was shaped by alliances between lords and vassals, forged through peaceful and violent means. We model coalition formation through bargaining or by conquest, and where members can rebel against their coalition. We derive conditions under which a realm unites under one rule — the grand coalition, or remains fragmented into several coalitions. We motivate our analysis with key historical episodes, from the Frankish Kingdom in the 5th to 10th centuries and England in the 11th to 15th centuries.
