Problem:Passage: Wallenstein is the popular designation for a trilogy of dramas by German author Friedrich Schiller. It consists of the plays Wallenstein's Camp , a lengthy prologue, The Piccolomini , and Wallenstein's Death . Schiller himself also structured the trilogy into two parts, with Wallenstein I including Wallenstein's Camp and The Piccolomini, and Wallenstein II consisting of Wallenstein's Death. He completed the trilogy in 1799. In this drama Schiller addresses the decline of the famous general Albrecht von Wallenstein, basing it loosely on actual historical events during the Thirty Years' War. Wallenstein fails at the height of his power as successful commander-in-chief of the imperial army when he begins to rebel against his emperor, Ferdinand II. The action is set some 16 years after the start of the war, in the winter of 1633/1634 and begins in the Bohemian city of Pilsen, where Wallenstein is based with his troops. For the second and third acts of the third play the action moves to Eger, where Wallenstein has fled and where he was assassinated on 26 February 1634.
