Before Nicholas III died in 1394, he had pledged Głubczyce, Zlaté Hory, Hlučín and Krzanowice to the Duchy of Oels.

Přemek also found himself in financial difficulties and had to pledge the Lordship of Hradec nad Moravicí to Wok Lacek of Krawarn.

Because Přemek sided politically with King Wenceslaus, he joined the Silesian League at the meeting in Wrocław in 1402.

Přemek's oldest son Wencelaus II managed to avert the destruction of Głubczyce by signing a treaty with the Hussites.

In March 1428, Přemek joined forces with Duke Rupert II of Lubin and the Bishop of Wrocław.

In December 1428, Přemek's son Wenceslaus participated in the Battle of Stary Wielisław, where the Hussites again prevailed.
