During Peru's internal armed conflict, the government of Alberto Fujimori launched a campaign-disguised as a family planning program-that resulted in the forced sterilization of thousands of women of poor, rural, and Indigenous-language-speaking backgrounds. Together We Fight explores Indigenous and non-Indigenous women's brutal experiences of forced sterilization and their subsequent activism for reproductive rights and justice. Nusta Carranza Ko draws on a vast trove of first-person testimony to amplify the neglected voices of victim-survivors, unpacking their ideas of justice and examining the work of allies that have accompanied them in their activism. Focusing on these women's stories and struggles, she argues that the campaign was genocidal.
