Nostalgia can serve as a vital tool in the emotional reconstitution and preservation of suppressed histories, rather than sentimentally privileging the past at the expense of present concerns and limiting a culture's progressive potential. Between 1936 and 1938, responding to a military coup in Spain led by Francisco Franco with the support of both Hitler and Mussolini, over 2700 US anti-fascists joined 30,000 volunteers from around the world to form the International Brigade. They came together to defend the democratically elected Spanish government against this early manifestation of the fascist Axis. After three bloody years, Franco's rebellion succeeded, and his dictatorship lasted until his death in 1975. From the moment the first American volunteers returned home, and to this day, they have been holding commemorative events recalling the struggle. For nearly seventy years, the Veterans of the Abraham Lincoln Brigade have cited and re-cited their activist past in theatrically eclectic, highly emotional commemorative performances, a site for both nostalgia and progressive politics. Literary recitations, scripted dramatic pieces, songs, films, photographs, and celebrity appearances have been juxtaposed with speeches, fundraising, and a rigorous attention to pressing political and social concerns of the day. The history and content of these events is detailed and analyzed here based on a combination of archival and ethnographic evidence. The exemplary role of songs from the war, as both nostalgic triggers and historical artifacts, is also examined. Commemorations of the Spanish Civil War have provided necessary anchors for a period in U.S. history when views now thought extreme were an accepted part of mass political discourse. Through this rich, inter-generational performance practice, a marginalized, vernacular political minority has deployed radical nostalgia as a necessary corrective to an official culture disinterested in America's leftist past, and threatened by its implications.
