Palaeoenvironmental, epigraphic and archaeological evidence of total warfare among the Classic Maya

Despite over a century of archaeological research, the nature and broader consequences of Maya warfare remain poorly understood. Classic period (250-950 CE) Maya warfare has largely been viewed as ritualized and limited in scope(1-6). Evidence of violent warfare in the Terminal Classic period (800-950( )CE) is interpreted as an escalation of military tactics that played a role in the socio-economic collapse of the Classic Maya civilization(7,8). The implications of specific textual references to war events (war statements) remain unknown, however, and the paucity of field data precludes our ability to test collapse theories tied to warfare. Here we connect a massive fire event to an attack described with a Classic period war statement. Multiple lines of evidence show that a large fire occurred across the ancient city of Witzna, coincident with an epigraphic account describing an attack and burning of Witzna in 697( )CE. Following this event, evidence shows a dramatic decline in human activity, indicating extensive negative impacts on the local population. These findings provide insight into strategies and broader societal impacts of Classic period warfare, clarify the war statement's meaning and show that the Maya engaged in tactics akin to total warfare earlier and more frequently than previously thought.
