The House of Waldstein or House of Valdštejn is a Bohemian noble family that originated from the Kingdom of Bohemia as a branch of the Markwartinger family (House of Markvartic[1]) and gained prominence during the reign of the Přemyslid dynasty. The house was founded by Jaroslav of Hruštice (1234–1269) and named after Valdštejn Castle near Turnov in northern Bohemia. The family's most prominent members include Albrecht von Wallenstein, the Imperial general during the Thirty Years' War, and Ferdinand Ernst von Waldstein, a statesman and early patron of Ludwig van Beethoven.
