 His humorous works were probably most popular, including "Ränzel und Wanderstab" (1821) and "Gelasius" (1826).He also wrote some well-received dramas, including "Schwur und Rache" (1826) and "Hans Kohlhaas" (1828).Another 1828 play, however, "Der alte Student", had a Polish protagonist and was judged to contain political agitation for Poland by the Prussian authorities, leading to his banishment from Berlin.
