Event ethnography is a methodological tool that involves ethnographic research on or at events. “Events” are activities, gatherings, and collective experiences that are limited in time and are highly diverse in their scope, organization, and thematic organization. Because of their temporary nature, events serve as unique venues for the convergence of actors who are usually spatially, temporally, and socially dispersed. Ethnographic research at events thus offers scholars a useful window onto how power relations are formed through the concentrated interaction among individuals, ideas, affects, and infrastructures. This article defines “event ethnography” and surveys the existing literature that examines events through ethnographic research. It suggests that taking events seriously for fieldwork has the potential to open up new questions for political geographers and other scholars interested in power and politics.
