Many feminists have been troubled by questions of friendship in ethnographic research. For some critics, such assertions elide power imbalances, invoking a 'sisterly identification' built on essentialist models of gender. In this article I combine insights gained from partisan ethnography in the Northern Ireland Women's Coalition with feminist theory to argue that the problem lies not with claims to friendship as such, but with a naturalized model in which friendship is treated as a power-free zone. A more politicized approach to friendship offers analytical tools for thinking about methodological, epistemological, political and applied problems in feminist anthropology and politics and to wider questions about the relationship between intellectual and political life, critique and solidarity.
