Wenceslaus of Niemodlin
Little is known about his early years of life. In 1364 Wenceslaus married with Euphemia (b. 1350/52 – d. 26 August 1411), daughter of Duke Bolesław of Bytom; by virtue of this union, he received the district of Gliwice, according to the inheritance treaty signed by his wife's grandfather, Duke Władysław of Bytom with the Kingdom of Bohemia.
After the death of his father in 1365, Wenceslaus and his brothers inherited Niemodlin as co-rulers, although the full government was exercised by the older brother, Bolesław II. Only after Bolesław II's death in 1368, Wenceslaus could take the full government over Niemodlin; however his reign was short-lived: he died just one year later.
