Despite his alliance, Mieszko didn't take an active part in Wenceslaus II's campaign against Władysław I the Elbow-high in 1292; however, he put his army at the King's disposal and later took part in the Battle of Siewierz. Mieszko was present at the coronation of Wenceslaus II as King of Poland in Gniezno in 1300. After the death of Wenceslaus II in 1305, Mieszko continued to support
