"Wallensteins Lager" by Friedrich Schiller is a dramatic prologue written in 1799. It serves as the opening to Schiller's Wallenstein trilogy, set during the Thirty Years' War in 1633. The play depicts life in the military camp of the powerful general Albrecht von Wallenstein, capturing the voices of common soldiers who praise their commander's leadership and the freedoms he grants them. Tensions rise when troops learn the emperor plans to transfer part of the army to Spanish Habsburg command, setting the stage for the conflict that unfolds in the trilogy's subsequent plays.
