At the age of 10 Władysław received his own prince court. Władysław formed a friendship with Adam Kazanowski and his brother, Stanisław. It is reported that young Władysław was interested in arts; later this led to him becoming an important patron of arts. He spoke and wrote in German, Italian and Latin. Władysław was liked by the szlachta (Polish nobility), but his father's plans to secure him the throne of Poland ("vivente rege") were unpopular and eventually crushed in the Zebrzydowski Rebellion (rokosz).
