Süddeutsche Monatshefte (""South German Monthly"", also credited as Süddeutscher Monatshefte) was a German magazine published in Munich between January 1904 and September 1936. After beginnings as an art and literary venue, liberal but highly critical of modernism, it made a turn toward politics before World War I. Especially supportive of German conservatism, it was also sympathetic toward Völkisch ideologists, and published propaganda in favor of militarist politicians such as Alfred von Tirpitz. Having for its founder and editor Paul Nikolaus Cossmann, an assimilated Jew, Süddeutsche Monatshefte was generally antisemitic—strongly so after 1920, when it hosted calls for racial segregation. Its publication of conspiracy theories such as the stab-in-the-back myth paved the way for Nazi propaganda, but Süddeutsche Monatshefte was more closely aligned with the mainstream right. It played a part in conspiratorial alliances supporting the policies of Gustav von Kahr, although it also had Conservative Revolutionaries among its core contributors. In its late years, Süddeutsche Monatshefte turned to Bavarian nationalism and Wittelsbach loyalism, becoming a target for the Nazi regime. Cossmann was imprisoned for dissidence, then deported for his Jewishness; Leo Hausleiter took over, leading Süddeutsche Monatshefte until its disestablishment in 1936.
