Since Benedykt Zientara's classic monograph on Henry the Bearded, there has been a common belief that the ruler's foundation campaign was aimed at including the monasteries in the great development plan of Silesia. Is this thesis still relevant after years of research on the economic activity of monasteries in Silesia in the Middle Ages? I will try to answer this question in my speech.
The aim of the presentation is to show how the princesses and duchesses of Upper Silesia (descending from the original line of Opole rulers) manifested their power. The seals of the rulers, their titles in documents, but also their participation in foundation politics, which was also a way of manifesting power, will be used.
