This study is a result of research devoted to the ruling court in the Middle Ages. Individual examples portray the ruling court of King Wenceslas II. (1283-1305). Here, the court is introduced as a social system, which is reflected in individual personalities, in the structure, representation and space. The social system and its fundamental features: structural-organizational elements and interaction, which form the basis of any social system, are emphasised as the only possible paradigmatic levels when forming a model definition describing a medieval court, which otherwise changes in time and space. In addition, different manifestations are displayed during the reign of each ruler following from the subjective approach of that ruler. Terminological terms familia, curia minor and major are analysed, as well as their use in historical sources. The second part is devoted to the mechanisms of communication, which the ruler's favours mediate at court. Benefit or profit for courtiers, and the ruler as well, are judged to be joint factors in all the activities at a ruling court.
