The housing crisis—and emerging squatters’ movement—shaped and gave a sense of urgency to debates about the meaning of social welfare during post-war reconstruction. During this period, local and national government officials, and ordinary people were attempting to re-build, but also to re-think the relationship between citizen and state, and what it meant to be French. This essay discusses how squatting families from diverse neighborhoods around France negotiated postwar plans for reconstruction, articulating as they did so the possibility of a new form of Republican social citizenship in France. More specifically, the paper considers the role of women squatters and activists within the movement and how they re-imagined and negotiated their roles as mothers, workers, and citizens.
