Organizational Form and Fragmentation in the Lethal Outcomes of Mexico’s Vigilante Mobilizations, 2012–2015

Abstract

In 2013, people in Michoacán and Guerrero, especially from rural areas, armed themselves against criminal cartels. Although their movements emerged from comparable contexts, their leaders and organizational forms differed in ways that affected their tactics and targets, as well as the timing of de-escalation. Whereas Guerrero’s leaders understood their struggle as defensive, Michoacán’s leaders were businessmen who saw themselves engaged in an offensive campaign. This partly explains why fatalities were greater there than in Guerrero. I further demonstrate that movement fragmentation led to lethal violence, and their organizational forms also contributed to dynamics of escalation or de-escalation in ways not fully appreciated by scholars. Specifically, the organizational form of Michoacán’s patron-sponsored autodefensas made them more vulnerable to lethal violence than were Guerrero’s community-sponsored organizations.
