This poster advertises the novel ‘Der Untertan’ (‘The Subject’) by Heinrich Mann (1871-1950), the first part of his trilogy, ‘Das Kaiserreich’ (‘The Empire’). The novel was banned in Germany during the First World War, owing to its criticism of the militarism and conservatism prevalent in Imperial German society. It was finally published, to much acclaim, in 1918. Heinrich’s younger brother, the novelist Thomas Mann, initially wrote in support of the war but later agreed with Heinrich. Both brothers left for America in the 1930s following the rise of the Nazis.
