A large mass grave from the Early Iron Age indicates selective violence towards women and children in the Carpathian Basin

Narratives about the motivations and conditions for mass violence as a persistent feature of conflict throughout human history have evolved in complexity and materiality. Victims of these events are key for understanding the evolution and transformative power of violent behaviour as it developed from simple intergroup conflict to more strategic mass violence. Here we present the results of a bioarchaeological study of 77 and biomolecular analysis of 25 individuals from a ninth-century BCE mass grave from Gomolava in the Carpathian Basin, Southeast Europe. The site is located at the interface of complex sociospatial relations, divergent cultural traditions and values, and competing ideologies of landscape use. We show that excessive lethal violence enacted mostly on women and children suggests a selective demographic bias. The people buried together shared few, even distant, genetic relationships, and so their killing presents striking evidence for an episode of cross-regional conflict and an underlying aggressive shift in power, violence and gender relations in the region. Gomolava provides evidence consistent with deliberate annihilation of select sections of a regional population as a motivation for mass violence behaviour in later prehistoric Europe. It also shines new light on the socioeconomic agency and importance of women and young individuals in later European prehistory.
