This thesis grounds its examination of the maras of El Salvador in the historical past (1971-1992) rather than the present, which constitutes a departure from current scholarship on the subject. This thesis revises our current understanding of the emergence and development of maras in El Salvador through the recovery, insertion and examination of key local events, conditions, and historical actors of the 1970s and 1980s. From signifying friendship and camaraderie prior to the late 1980s, the maras increasingly became the target of public concern and Salvadoran security forces over the course of the 1980. By the late 1980s the maras increasingly became associated with criminal activity in Salvadoran society and popular culture. To document these changed conditions, this thesis relies extensively on previously untapped and ignored primary sources: newspapers and oral history interviews.
