Władysław of Cieszyn
Władysław of Cieszyn (1325/1331–1355) was the eldest son of Duke Casimir I of Cieszyn and Euphemia of Masovia. Destined for the Church, he became a close companion of Charles IV and attended the Bohemian court from 1347.
In 1354 Charles named him a court judge, and in 1355 he joined the Italian expedition and the imperial coronation in Rome. He died at Pisa later that year, possibly by poison.
