In the wake of the September 11, 2001 attacks, and in the midst of the subsequent nationalist fervor, Boston radicals came together to form the Boston Anarchists Against Militarism (BAAM) Coalition. Through interviews and an extensive study of BAAM's public statements, activities, and publications, this history explores the evolution of BAAM from an anti-war coalition into a general union of Boston anarchists. The lessons of the past decade are useful to today's generation of activists as they grapple with the questions of political organization and activity in the struggle against global capitalism.
