Scholars identify the Cold War as a window for examining the allied relationship between the Philippine and US governments against communism. Recent scholarship shows that these conditions also produced another type of relationship between activists in both countries that contrasted that of their governments: one of anti-imperialism, nationalist solidarity, and communist visions. In this paper, I examine transnational intimacies developed between women involved in the opposition movement against Ferdinand Marcos during the 1970s and 1980s. In the safety of “revolutionary friendship,” anti-Marcos activist women grappled with intimate experiences of state violence, sexism, homophobia, and racism, as well as emergent global ideas about feminism, anti-imperialism, and nationalism. Their collective observations revealed to them limitations within the nationalist paradigm they were utilizing. Grounded in revolutionary friendship, their transnational letter exchanges, original essays, and research projects helped them to theorize a new “nationalist feminism” for the Philippines that integrated gender, class, sexual, and national liberation.
