Abstract: | The prominent presence of noble families in towns is generally accepted as a distinguishing feature of medieval Italy's communal city-states. Paradoxically, the nobility, as the exclusive supplier of trained and fully equipped cavalrymen, would retain a pivotal position in the communal armies when, in the Duecento, their political power was questioned. In this article a detailed study has been made of the nobility's role in the organisation of the ac]cavallata (the public obligation to maintain warhorses) as well as in the militia (cavalry service) of the Umbrian town of Todi in the decades around 1300, when Todi as a city-state reached the zenith of its power. It is argued that in Todi cavallata and militia did not coincide in all respects, and also that both institutions were to some extent open to members of the sizeable class of the sergentes. The sergentes were responsible for the ‘rural’ part of the cavallata, and they provided the cavalry of the communal army with light horsemen. |
