Henryk IV Probus
Historians do not agree why Przemysł II replaced the seal used by his father and uncle for a lion and an eagle. It is believed that either he wanted to emphasize his precedence from the Piast dynasty (the eagle in the coat of arms was also used by Władysław III Spindleshanks and Władysław Odonic), or with the symbol wanted to emphasize his rights inherited from Henryk IV Probus.
