The biography of the educational citizen, German-national conservative, scholar, and officer Dr. phil. habil. Hans Jüngst (1901-1944), born around the turn of the century, encompasses precisely the period of the German Age of Extremes. It is based on an impressive collection of sources from the estate of Hans Jüngst, which offers significant insights into mentalities: private, war, and field post letters, diaries, notes, and documents from the entire first half of the 20th century. Through this estate, the present biographical study traces the end of the German Empire, the decline of the Weimar Republic, the rule of National Socialism, and World War II from a historical perspective focused on everyday life. An appendix includes a selected edition of field post letters from the correspondence between Hans.
