Isotopes of strontium, oxygen, and carbon were analyzed in human tooth enamel from two Postclassic sites in the central Peten lakes region, Guatemala, to examine patterns of mobility and diet during a time of social unrest. Excavations at both sites, Ixlu and Zacpeten, have revealed evidence for purposeful dismemberment and interment of individuals. This study examines a possible shrine surrounded by rows of skulls at Ixlu, and a mass grave of comingled individuals interred at Zacpeten. The interments coincide with a period of conflict and warfare between two dominant polities, Itza and Kowoj. The 14 sampled individuals at Ixlu were young males, six of whom isotopically match the Maya Mountains of central Belize/southeastern Peten. At Zacpeten, isotopic signatures of adults and children (n = 68) suggested that many were either local or came from other parts of the Maya lowlands, but not the Maya Mountains. In the Late Postclassic, the Zacpeten individuals were exhumed, defiled, and deposited in a mass grave, probably by Kowojs. Although temporally and geographically related, the Ixlu and Zacpeten burials represent two distinct cases of ritual violence that reflect the tumultuous political landscape of the Postclassic period.

Nonviolent resistance against rebels has received increasing scholarly attention over the past decade. Research has explained why and when civilians engage in resistance or place different types of demands on rebels. However, the question of whether nonviolent resistance succeeds or fails to achieve its objectives remains understudied. This article addresses this gap by theorising and testing three key factors that shape rebel responses to civilian resistance: the nature of civilian demands, the power of civilian resisters, and the rebels’ own power. Fieldwork in Colombia’s Caquetá region reveals that FARC rebels accommodated civilian demands only when these did not threaten their strategic goals. The group responded with repression whenever resisters clashed with its politico-military objectives. While unarmed resistance campaigns have successfully overthrown repressive states, there is no evidence for civilians in Colombia or elsewhere managing to push armed groups to make far-reaching concessions, let alone defeat rebels via nonviolent action only.

The 1970s was the most violent decade of the entire twentieth century for Argentina. Its first half was characterised by the rise of political radicalisation, and its second by the reign of state repression. Studies devoted to investigating the issue of violence in the 1970s have concentrated fundamentally on the protagonists. By contrast, this article offers an analysis of the symbolic terrain, shifting focus from the conscious to the unconscious plane, from the real to the imaginary world. Dealing with visual representations of violence in popular culture, especially advertising in mass-circulation magazines, it explores how violence became naturalised during the first half of the 1970s. In so doing it adds an additional layer to our understanding of the social mood that preceded the military coup of March 1976.

Using interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.
