This master s thesis examines women who were arrested and imprisoned for crimes regarded as political between 1968 and 1979. These events took place in two specific venues: Talavera Bruce Penal Institute, in the state of Rio de Janeiro, and Tiradentes Penitentiary, in the state of São Paulo. A wide range of elements intertwine between their detention and their imprisonment in those two institutions. These events include their political projects and the different revolutionary left-wing organizations they joined, the society in which they lived that created extremely specific gender roles, and even the way in which the Women s History field provides the lenses through which this history is developed. Therefore, this dissertation aims to analyze the incarceration of these female political prisoners in these two prisons. I consider the moment they entered the world of revolutionary left-wing organizations and their passage through the organs of repression as chapters of their lives. Inside these prisons, I identify issues that relate gender and imprisonment in an exception regime, analyzing differences in the treatment of imprisoned women in relation to their male counterparts. Such differentiation includes the prison space itself and then the symbolic relations established in it. Here we can insert women s adaptation to an architectonic space projected for the male gender, which did not have a physical structure capable of encompassing typically female issues, such as pregnancy. Thereby, this work investigates the differences of experience – physical and psychological – related to female imprisonment. I also draw parallels between political and common female prisoners that were locked up in these two prisons.
