description: "Piotr Włostowic, also known as Peter Wlast, was a Polish noble, castellan of Wrocław, and a ruler (możnowładca) of part of Silesia. From 1117 he was voivode (palatyn) of the Duke of Poland Bolesław III Wrymouth. Part of the Łabędzie family, and son of Włost, he is likely to have been related to older princes of Silesia. His lands included the territories near Mount Ślęża and Piasek Island near Wrocław. The Dunin clan of noble families claims descent from him."
