To strengthen his son's position, Wenceslaus II of Bohemia came to Hungary at the head of a large army in May 1304. He captured Esztergom, but his negotiations with the local lords convinced him that his son's position in Hungary had dramatically weakened. Accordingly, he decided to take Wenceslaus-Ladislaus back to Bohemia. Wenceslaus-Ladislaus did not renounce Hungary and made Ivan Kőszegi governor before leaving for Bohemia in August. He even took the Holy Crown of Hungary with himself to Prague. Charles of Anjou and Rudolf III of Austria invaded Moravia in September, but did not defeat Wenceslaus II's army. In the same months, a member of the Piast dynasty, Władysław the Elbow-high, who had claimed Poland against Wenceslaus II, returned to Poland at the head of Hungarian troops. Before long, he captured many important forts and towns, including Pełczyska, Wiślica, Sandomierz, and Sieradz.
