Just how alien were the barbarians in the late Roman Empire? If you have visual images of fur-clad screaming warriors beating up clean-shaven and well-coiffed toga-wearing Romans after reading that sentence, no shade, but you are behind in your Ancient Roman history studies. By the time of the Western Empire’s collapse in the 5th century, barbarians had been integrated into Rome’s borders, as a new study published in the science journal _Nature_ shows.
This past April of 2026, _Nature’s_ analysis detailed a longitudinal genetic study of 258 skeletons from the Empire’s north-west borderlines that dates from the 450s to the 620s. Over 150 were from a settlement at the modern-German town called Altheim, and an example of one of these “Row-graves” that typified these burials is shown here.
What the study demonstrates is that, starting well before the fall of Rome’s Western Empire in the late 5th century, there was increasing genetic mixing of people of “barbarian” (ancestors of Germanic-speaking peoples) and Romans. Both of these populations had more in common with each other than they would have with the urbanized or elite Romans who lived in the cities of the Italian peninsula. They would have been farmers, equally aware of the levels of political chaos and warfare that had riddled the area since the 200s. They exchanged goods with each other, had similar mortality rates, and shared the same types of physical environments. Eventually, they were sharing more than that, as they began blending families and having children together.
What I wish I could know is the degree to which this blending was conscious — or was it becoming irrelevant by the fall of the Western Empire who was Roman and who was barbarian along the northern frontiers?
