Frieda von Bülow was a colonialist woman author and activist who also engaged the bourgeois women's movement of pre-First World War Germany. She is of interest to scholars of German colonialism, racial thought, feminism, and women's literature. This article interprets her life experiences, including travel to German East Africa (mainland Tanzania) and her affair with Carl Peters, together with her feminist non-fiction and anti-feminist fiction, to argue that she developed an imperial feminism in which German women's emancipation was predicated on the subordination of racialised ‘others’.
