German "Moritzian"-inspired stories include "Lies und Lene; die Schwestern von Max und Moritz" (Hulda Levetzow, F. Maddalena, 1896), "Schlumperfritz und Schlamperfranz" (1922), "Sigismund und Waldemar, des Max und Moritz Zwillingspaar" (Walther Günther, 1932), and "Mac und Mufti" (Thomas Ahlers, Volker Dehs, 1987). These are shaped by observations of the First and Second World Wars, while the original is a moral story. In 1958 the Christian Democratic Union used the "Max and Moritz" characters for a campaign in North Rhine-Westphalia, the same year that the East German satirical magazine "Eulenspiegel" used them to caricature black labour. In 1969 "Max and Moritz" "participated" in late 1960s student activism.
