Sometime between 2880 and 2776 BCE, 15 family members were hastily buried together in a single pit, their shattered skulls telling a story of violent death. Yet someone interred the dead with the pottery, tools, and ornaments typical of a proper burial in their culture, a culture we know today by the name of its most common ceramic artifact: the Globular Amphora. And someone seems to have made the effort to put the closest family members alongside one another in the pit.

Today, the grave near the village of Koszyce in southern Poland is the only record of one particular act of brutal violence during a turbulent time in European prehistory.

Out of the blue

It seems that no one in the seasonal camp of pastoralists was prepared for the raiders. Nearly all of the dead are women and children. Though women in the past (and today) could be formidable fighters, no weapons are buried with them to suggest that was the case here. Almost none of their bones show signs of broken limbs raised in defense (known as parry fractures), so it doesn’t look like they went down fighting. Instead, most appear to have died from crushing blows to the back of their skulls, as if they’d been captured and executed.
