When Henry IV Probus took control over Kraków after the death of Leszek II the Black in 1288, he could count on the support of the Duke of Ścinawa.
The key to the interpretation of both sources, could be found in the Duke's grave in the Cisternian monastery of Lubiąż, who was possibly the main cause of the description of Przemko's dramatic end.
It is there were the Duke of Ścinawa was buried; also, just before to his departure to the battle, he ordered two of his villages: Łososzkowice (now Łososiowice) and Żyrków (now Żerków), to provide storage and support to the Cistercians.
It is doubtful that Władysław I the Elbow-high and Bolesław II of Płock, or any knight, could murder Przemko in cold blood.
Przemko never married or had children; according to the Feudal Law, Ścinawa was annexed by Henry IV Probus to his domains, as part of his projected unification of Poland.
During his reign, Przemko granted the Magdeburg Law to five Silesian towns: Żagań, Lubin, Przemków, Wołów and Wińsko.
The exact foundation of Lubin and his early history is not entirely known, but previous studies assumed the city existed already in 1170, but was formally founded by 1202.
In a document confirming the possessions of Lubiąż monastery in 1217 existed a record of "Wroblino juxta vin", which, by some scholars, is regarded as the earliest mention of Wińsko.
