New Wars, Old Wars, and Medieval Wars: European Mercenaries as State Actors in Europe and North Africa, ca. 1100–1500

Medieval European mercenaries are often seen as impediments to state formation because European monarchies found them expensive and difficult to control. By taking a broader comparative approach to their deployment that encompasses North Africa, I show that these soldiers could serve as effective agents of state power. Abandoning the mercenaries is sometimes represented as a positive break with the medieval past that accelerated European progress into the modern political order of states and standing armies. From a comparative point of view, however, this transition looks more like a gradual retreat from a system for organizing violence that continued to function well in other parts of the world.
