The Cold War had a variety of impacts on Swiss schools. This article focuses on how schools, and especially their history curricula, became the vehicle with which to launch a “National Spiritual Defense“ (Geistige Landesverteidigung) against Communism. During the Cold War era, especially in the 1950s and 1960s, teachers' journals and textbooks analyses revealed tendencies connected to a heroic, teleological master narrative of Switzerland's national history. The “cultural memory“ (Assmann) was seemingly designed to strengthen the “Swiss spirit.“ It also provided patterns from which to explain the ongoing Cold War conflict. In the 1970s, educators and politicians assigned the schools the new task of assisting in national military defense efforts.
