This list covers the period from the accession of Pope Leo IX until the rise of the condottieri. Perugian, Romagnol, Anconan, Tuscan or Spoletan contingents are treated as allies from III/73, because of the casual attitude of those cities to their military obligations. Luckily the popes had money to hire mercenaries. References: Armies of Feudal Europe 1. Heath.
