Władysław of Bytom
Władysław of Bytom (1277/83–1352) was a Silesian Piast duke who ruled Koźle from 1303 and Bytom from 1316. The second son of Casimir I, he reunited his father's scattered lands, but money troubles forced him to sell Siewierz in 1337 and pledge Koźle to Racibórz.
In 1327 he did homage to King John of Bohemia at Opava, but during the Polish–Bohemian war of 1345–1348 he fought on Poland's side. He died in 1352, leaving Bytom to his son Bolesław.
