In the early middle ages the court was a centre for meetings of secular and clerical princes. At the court of emperors, kings, and popes, the princes of different lordships met and the court was therefore at the centre of conflict. The court as centre of rule is especially important at the moment when the cooperation at the court is questioned by escalating quarrels. In the situation of conflict the notions of the princes emerge more clearly, the implicit demands the princes were subordinated to as well as the political mode of functioning at the court. In situations of conflict the mechanism of culture of debate in the early middle ages can be observed. Different aspects of conflict at court in the early middle ages were discussed at this international congress.
