[1] After his father's death in 1281 or 1282, Przemysław and his brother Mieszko I received the districts of Racibórz, Cieszyn and Oświęcim.

In 1287 Henry IV made a retaliatory expedition against Racibórz, who was sieged and almost destroyed.

Przemysław retained the main city of Racibórz and Mieszko I obtained Cieszyn and Oświęcim.

In the internal politics, Przemysław made two important events in his lands: in 1299 he granted urban privileges to the city of Racibórz and founded a Dominican monastery there.

Leszek, as the only son, inherited the whole duchy, except Wodzisław Śląski, who was given to his wife Anna as her dower.
