Henryk IV Probus
This alliance probably forced Bolesław the Pious to reconsider his treatment of his nephew and finally granted him the Duchy of Poznań in 1273. Przemysł II, in exchange, not only interrupted for a time his cooperation with the Duke of Wrocław, but decided to support his uncle in the expedition against Władysław of Opole (ally of King Ottokar II and Henryk IV Probus), in retaliation for the attempts of the Opole ruler to overthrow the government of Bolesław V the Chaste in Lesser Poland during the first half of 1273. Thus, with high probability, it can be concluded that by this time the conflict between Przemysł II and his uncle for power has been finally resolved.
