The exercise of power was not evenly distributed in space and time in the Middle Ages (and in other eras as well), and the torso records can only identify the days and places of the king's presence for a fraction of the reign, usually less than 10%. A novel approach to this problem has been taken by Eckhardt Müller-Mertens (1923-2015), who has offered a method that can bridge these weaknesses and offer a comprehensive assessment of the reign of a given monarch. In order to use this method for the reign of Přemysl Ottokar II, we had to reconstruct the missing itinerary and regesta of his reign, which consists of 980 items, as well as a comprehensive record of persons present at the court (over 3000 records). In particular, attention will be paid to the question of how the king's itinerary and the intensity of his monarchical activities changed in the context of his founding deeds and the current political situation. The paper will also present a comprehensive evaluation of the prosopographical analysis of the persons present at Přemysl's court.
