This essay explicates Mary Austin's theory of citizenship and demonstrates her contribution to the larger literature on social democratic citizenship emerging in the early twentieth century. The primary text considered is her monograph,The Young Woman Citizen (1918). In this piece, Austin reimagines the spatial and gender ordering of the polity to create an integrative and inclusive civic ideal. She employs the concepts of society and mind as a means of blurring the boundaries between the public and private and integrating the polity, while she turns to woman-thought, social capital, and the generative state to secure women's inclusion. Austin's work combines a unique form of the gender-difference argument for suffrage with progressive political philosophies in an effort to construct a model of the polity in which women share sovereignty with men, socially, culturally, and institutionally.
