In 1306 he paid homage to his uncle Władysław I, in return for which he was appointed Governor of Gdańsk Pomerania, with his base in Świecie.
In addition, he tried without success to recover from the Teutonic Order the Michałów Land (with money received from Gerward, Bishop of Kujawy).
In 1314 was made the formal division of the paternal inheritance between Przemysł and his brothers; he received the northern part of the Duchy, with the main districts of Bydgoszcz and Wyszogród.
Between 1320/24 Leszek unexpectedly abdicated the government, leaving all the Duchy to Przemysł, who in 1325 granted the Magdeburg Law to the district of Solec Kujawski.
Przemysł died between November 1338 and 16 February 1339, because witnesses of the Polish-Teutonic trial refers to him as recently deceased at this point.
