Casimir of Koźle

Casimir of Koźle (c. 1312–1347) was Duke of Koźle in Upper Silesia from 1336 until his death. The eldest son of Władysław of Bytom and Beatrix of Brandenburg, he received the district from his father in 1336.

Burdened by heavy debts, he stopped paying Peter's Pence, for which the Church excommunicated him. He died unmarried and childless in 1347, and Koźle passed to his younger brother Bolesław.
