During the interwar period, internationalists declared Hawai‘i the “new Geneva” of the Pacific: a locus for regional diplomacy, social reform, and cross-cultural exchange. This talk examines the Pan-Pacific Women’s Association (PPWA), part of the Honolulu-based Pan-Pacific internationalist movement. The Pan-Pacific Women’s Association enacted social reform grounded in ideals of anti-racism, affective connection, and cross-cultural exchange. Endorsed by prominent U.S. social reformists like Jane Addams, the association promoted the praxis of “open-minded cosmopolitanism,” organized local chapters, and convened annual conferences related to education, healthcare, and gender. Although largely unexamined in scholarship on internationalism, this presentation recuperates “friendship” in two ways: first, as a fundamental tenet of Pacific interwar internationalist praxis; and second, as an analytic attuned to internationalism’s entanglements with empire, race, gender, and sexuality. Pan-Pacific “international friendship” was characterized by a social, intellectual, and cultural solidarity largely forged through the interpersonal and affective. This presentation argues that in spite of the PPWA’s progressive antiracist liberal cosmopolitanism, the ideology and practice of international and interracial friendship often consolidated, rather than dismantled, hierarchies of race, nationality, class, gender, and sexuality.
