This article re-examines a controversial group in English religious history: the millenarian followers of the prophet Joanna Southcott. The identities of many of Southcott's supporters have remained unclear, despite notable academic attention. Their relative social dislocation is most disputed; greater consensus characterises debates over women's attraction to Southcottianism. This article uses a recently-opened archive of Southcottian material, and reinterprets previously-known sources, to revise all existing pictures of who Southcottians were. Southcottian occupations in industrial regions indicate a similar social makeup to contemporary Methodism; Southcottianism had no distinct appeal to women. New evidence of the personal experiences of Southcottians further suggests that they may be best understood as a branch of the ‘heart religion’ of the period, one taking a distinctive view of the ways and means of direct communication between the divine and human worlds.
