Вацлав IV
After the death of King Wenceslaus IV of Bohemia, Queen Sophia (with the help of Čeněk of Wartenberg) tried to gain control of Prague. Sophia and Čeněk recruited soldiers from Germany, who took up positions at Vyšehrad, Hradčany, and at the archbishop's palace and the cloister of St. Thomas in a part of Prague called New Town. The Hussite uprising was successful in other parts of Bohemia, and the towns of Klatovy, Písek, Louny, Žatec, and Plzeň came under Hussite control. On 25 October 1419, Hussites captured Vyšehrad as well.
