The first two decades of the twentieth century saw the development of a meaningful transnational movement to employ birth strikes in the fight for women's rights. In an Anglo-American context, this movement was intimately tied to the women's suffrage campaign. It was led by a network of suffragists, Neo-Malthusians, and birth control campaigners who shared literary and personal ties which allowed their ideas to criss-cross the Atlantic between 1911 and 1920. Although the transatlantic birth strike was never implemented on a significant scale, explaining its almost total absence within existing historiography, this article uses a gendered intellectual history framework to piece together the ideas behind the movement which, the article argues, disrupt established understanding of Neo-Malthusianism and socialist-feminism within intellectual histories. Support for birth striking was predicated on faith in the power of working-class collective action, scrutiny of the economic exploitation of both productive and ‘reproductive’ workers, and a corresponding mistrust in the efficacy of state involvement with these issues. The birth strikers wove together strands from collectivist, individualist, socialist, and feminist thought, undermining traditional historiographical depictions of binaries between socialism and suffragism and collectivism and individualism in early twentieth-century political thought.
