IOGRAPHY Hynek (Heinrich) was the son of Zdenko 'der Lange' von Waldstein zu Stjepanicz and Katharina von Kostalow. With his wife Agnes von Kunstat und Podiebrad, daughter of Viktoryn von Kunstat and Anna von Wartenberg, he had a son Heinrich who would have progeny.

Heinrich fought on the side of the Hussites at the conquest of Vysehrad (Wyschehrad) and in 1426 at their victory over the army of the margrave of Meissen at Usti nad Labem (Aussig). He was lord of the castle of Koldstejn (Goldenstein) in northern Moravia. One of the leading supporters of the Utraquist movement, he campaigned for the right of the king of Poland, then Wladyslaw II Jagiello, to become king of Bohemia, placing him in opposition to Emperor Sigismund. He was killed in Prague in 1427 during an attempt to seize the city for the Lithuanian prince Sigismund Korybut, a nephew of Wladyslaw II Jagiello, and military leader of the Hussites.
