This thesis is an exploration of the symbolic dimensions of activism in the SOA Watch movement, which seeks to close the School of the Americas (SOA), a U.S. training facility for Latin American military and police. Through historical analysis, participant observation, and ethnographic interviews with activists, I examine the practices of activism in the SOA Watch movement and the systems of meaning that inform them. As activists in the movement engage a system of power they seek to change, they construct and locate this system in space and time. By inserting themselves into the history and geography of the SOA through practices of resistance, activists construct and enact their own agency.
