Simplicissimus (German: [zɪmplɪˈtsɪsɪmʊs]) was a satirical German weekly magazine started by Albert Langen in April 1896 and published until 1967, with a hiatus from 1944-1954. It became a biweekly in 1964. It took its name from the protagonist of Grimmelshausen's 1668 novel Der Abenteuerliche Simplicissimus Teutsch. The headquarters was in Munich.
Combining brash and politically daring content, with a bright, immediate, and surprisingly modern graphic style, Simplicissimus published the work of writers such as Thomas Mann and Rainer Maria Rilke. Its most reliable targets for caricature were stiff Prussian military figures, and rigid German social and class distinctions as seen from the more relaxed, liberal atmosphere of Munich. Contributors included Hermann Hesse, Gustav Meyrink, Fanny zu Reventlow, Jakob Wassermann, Frank Wedekind, Heinrich Kley, Alfred Kubin, Otto Nückel, Robert Walser, Heinrich Zille, Hugo von Hofmannsthal, Heinrich Mann, Lessie Sachs, and Erich Kästner.
