 Institutions, such as monasteries or churches were also required to send soldiers to fight based on the wealth and the amount of lands they held.In fact, the use of ecclesiastical institutions for their resources for the military was a tradition that the Carolingians continued and greatly benefitted from.It was “highly unlikely that armies of many more than a hundred thousand effectives with their support systems could be supplied in the field in a single theatre of operation.” Because of this, each landholder would not be required to mobilize all of his men each year for the campaigning season, but instead, the Carolingians would decide which kinds of troops were needed from each landholder, and what they should bring with them.
