Wenceslaus received Przewóz together with his brother Jan II as a co-ruler.
Because of his mental illness, Wenceslaus didn't participate in the political life.
In 1454 Jan II became Wenceslaus's legal guardian and was obliged to ensure him an adequate lifestyle.
In 1472, when Jan II sold the Duchy of Żagań to the rulers of Saxony, Ernest and Albert, Wenceslaus received 2,100 florins as a pension.
In 1476 Wenceslaus renounced to his claims over the Duchy of Głogów for a rent of 400 guilders and moved to Wroclaw, where he entered the monastery of St. Barbara.
