This project tackles the history of the women group of the HOAC (Workers' Brotherhood of Catholic Action) during Franco dictatorship and the transitional period to democracy in Spain through oral sources. This is a necessary methodology in order to analyze the public participation and social commitment of the Catholic working women, thanks to their personal experiences as HOAC members. Additionally, the personal stories of the HOAC women are an essential source to study not only the evolution of the organization, but also the difficulties that this group suffered considering that gender roles, as defined by the Church and Regime, marked and limited their field of action. Finally, the present project sheds light on the individual evolution of many women who became aware of their inequality through the courses and activities organized by the HOAC, thanks to which they began to participate, like their male counterparts, in the trade unions and social struggles during the last decades of Franco dictatorship.
