Effi Briest by Theodor Fontane (1896). In the confrontation between Geert von Instetten and Major Crampas, Instetten challenges Crampas to a duel after discovering that his wife Effi had an affair. The duel is framed as a matter of honor, duty, and adherence to societal rules. Instetten’s actions are driven not by personal anger but by a sense of obligation to maintain social order and follow protocol. The focus on duty, principle, and maintaining the integrity of agreements underscores the German tendency to adhere strictly to social norms and established structures.
