Sacred Profits: The Institutional Economics of Holy War
Key Insights#
- Religious institutions serve as powerful coordination mechanisms that reduce transaction costs for elite-benefiting projects by providing legitimation, organizational infrastructure, and enforcement capacity.
- The Crusades generated substantial economic returns for the Church, Italian merchants, and nobility through taxation, trade monopolies, and land acquisition, despite frequent military failures.
- Systematic divergence between stated religious objectives and achieved material outcomes reveals institutional optimization for resource accumulation over doctrinal consistency.
- The coordination mechanism persists across contexts, from medieval crusading to modern resource conflicts, whenever elites need mass mobilization without direct compensation.
