Wenceslaus of Płock
From Wikipedia, the free encyclopedia
Wenceslaus (Wańko) of Płock (Polish: Wacław Płocki, Masovian dialect: Wańko Puocky; 1293/97 – 23 May 1336), was a Polish prince member of the House of Piast, Duke of Płock from 1313 and vassal of Bohemia from 1329.
He was the third son of Bolesław II of Płock but the only born from his second marriage with Kunigunde, daughter of King Ottakar II of Bohemia.[1] He was probably named after his maternal uncle, King Wenceslaus II of Bohemia.
