This book presents a history of radicalism in both parts of Ireland from 1956-1973 by charting the interaction between feminism and republicanism, civil rights advocacy, housing activism, and left-wing politics. It brings together an analysis of women's roles within the wider spectrum of Irish radicalism throughout Ireland, Britain, and the US. In the Republic, the threat involved equal pay and family planning while in Northern Ireland the threat had less to do with issues and more to do with action. The introduction of gendered security tactics like Internment for men ensured that women leaders would emerge. These women created activist networks that redefined their roles as women in Irish society. Together, these women presented a damning critique of the traditional gender contract and through their work they demonstrated that a new concept of womanhood was possible.
