Federici's most influential work argues that the transition to capitalism required not only the enclosure of common lands and the disciplining of the waged workforce but the simultaneous construction of a new gender order through systematic violence against women. The witch hunts of the sixteenth and seventeenth centuries, which killed tens of thousands of women across Europe and its colonies, were not episodes of superstitious hysteria but coordinated campaigns of social engineering. They targeted precisely the women whose autonomy, knowledge, and economic independence threatened the gendered division of labor that capitalism required: healers, midwives, women who controlled their own reproduction, women who participated in communal land management, women whose subsistence did not depend on male wages.
The book's argument unfolds across three interconnected transformations. The enclosure of common lands destroyed women's economic autonomy by eliminating access to the resources — fuel, food, grazing rights — that had enabled subsistence independent of wages. The witch hunts destroyed women's bodies as sites of knowledge, pleasure, and communal authority, reconstructing them as machines for reproduction that the state and capital could regulate. The legal and ideological campaigns subordinated women to male household heads, ensuring that women's labor would be extracted through the domestic relation rather than through direct wage contracts. The three processes were mutually reinforcing, and their cumulative effect was the creation of the gendered division between productive and reproductive labor that has structured capitalism for five centuries.
Federici identifies the witch as the paradigmatic figure of resistance to primitive accumulation — the woman who possessed knowledge of healing, contraception, and abortion; who participated in communal decisions about land use; who earned income through her own skills; who refused subordination to male authority. The witch hunts eliminated this figure from European society with a thoroughness that genocide achieves. The violence was not incidental to capitalist development. It was foundational. The terror the witch hunts produced disciplined generations of women into acceptance of roles that their grandmothers would have found intolerable.
The book's contemporary relevance lies in its demonstration that primitive accumulation is ongoing. Every phase of capitalist expansion requires new enclosures, new forms of violence against those who resist, and new mechanisms for extracting labor that the wage relation does not cover. Federici traces this pattern through colonial conquest, through the construction of racialized labor hierarchies, through the contemporary debt economy that extracts value from populations in the Global South. The AI enclosure of the creative commons and the intensification of reproductive labor demands follow the same structural logic that Caliban and the Witch identified at capitalism's origins.
The witch, in Federici's reading, is not only a historical figure but a persistent category — anyone whose autonomy threatens the system of extraction. The programmer whose code trains the model that replaces her, the artist whose style is absorbed by diffusion models, the care worker whose labor is systematically devalued despite its irreplaceable necessity — these are the contemporary inheritors of the witch's structural position: possessing knowledge that capital requires, subject to appropriation, excluded from compensation, and rendered invisible by accounting systems designed to conceal their contribution.
Federici began research on the witch hunts in the 1980s while teaching in Nigeria, where she encountered women's subsistence struggles and recognized structural continuities with the European transition to capitalism. The book was published in 2004 by Autonomedia after decades of archival research, field work with commoning communities, and theoretical development. It has become one of the most influential works in contemporary Marxist feminism and a foundational text for understanding the gendered character of capitalist accumulation. The book's reception established Federici as a leading theorist of the relationship between gender, labor, and capital.
Witch hunts were campaigns of social engineering. The systematic violence against women was not superstition but a coordinated political project to destroy women's economic autonomy and reconstruct their bodies as reproductive machines.
Primitive accumulation has a gender. The transition to capitalism required not only the enclosure of land but the disciplining of women's bodies and the creation of a gender order that would enable the extraction of unwaged reproductive labor.
The body is a site of political struggle. Capitalism's regulation of women's reproduction — through the criminalization of contraception and abortion, through the medicalization of childbirth — is continuous with its regulation of labor: both serve accumulation.
The witch is a structural position. The figure whose knowledge and autonomy threaten the system of extraction persists across historical periods — from the medieval healer to the contemporary creative worker whose collective knowledge capital appropriates.
