Wallenstein, Albrecht Wenzel Eusebius von, duke von Friedland

 later Duke von Mecklenburg

(born Sept. 24, 1583, Hermanice, Bohemia—died Feb. 25, 1634, Eger) Austrian general. A noble of Bohemia, he served with the future Habsburg emperor Ferdinand II in the campaign against Venice in 1617. He remained loyal to Ferdinand when other Bohemian nobles revolted (1618–23) and was made governor of Bohemia and allowed to acquire vast holdings in confiscated estates. Created duke of Friedland (1625), he commanded the imperial armies in the Thirty Years' War. After successes in the war against Denmark (1625–29), he was awarded the principality of Sagan (1627) and the duchy of Mecklenburg (1629). Under pressure from the German princes, Ferdinand was forced to dismiss Wallenstein. Recalled to imperial command in 1631, he drove the Swedish army from Bavaria and Franconia but was defeated at the Battle of Lützen (1632). Believing he had the support of his generals, he mounted a revolt against the emperor (1634) and was assassinated.
