What was the genetic legacy of the Roman Empire on the territories it controlled? At its peak in the 2nd century AD, the Roman Empire controlled roughly 20% of the world's population at that time. In my last video, I looked at the genetic makeup of ancient Rome itself, but in this video I am going to look at the genetic legacy of the empire more broadly.

Now there has been lots written on the legacy of the Roman Empire in general, from improvements in sanitation to architectural, engineering, legal, political, linguistic and countless other areas of life that ancient Rome influenced. But little have been said about genetics? What impact did one of the greatest empires in human history have on the genetics and ancestries of people who were under the Roman yoke?

Now lets start with Britain. Roman influence on Britain began in earnest with the invasion of 43 AD and Roman occupation lasted for nearly 400 years, until AD 410. The Roman occupation of Britain was not necessarily smooth, exemplified by the fact they had to build two major defensive walls on these lands to solidify their position, Antonine’s Wall in modern Scotland close where I grew up and Hadrian’s Wall in the north of modern England, which was built, as the biographer of Hadrian famously said, “to separate the Romans from the barbarians.”

Considering that the Romans occupied Britain for hundreds of years, you would perhaps think they would have left their genetic mark on these lands, but did they? Well the People of the British Isles study looked at how different migrations and invasions changed the genetic makeup of Britain over the centuries and millennia. It seems however that there is a very limited genetic legacy of the Romans in Britain. One theory why this is the case is potentially because only small numbers of Romans actually settled long-term in Britain.

Furthermore, many have argued that even in parts of Britain that were technically under Roman control, many rural parts of Britain could have been relatively unaffected by Roman rule on a practical, day-by-day basis, and were able to live quite similarly to before. The Romans would have also been quite concentrated in their fortresses and major towns, and perhaps didn’t interact to much with the natives. When the occupation ended in the 5th century as well, the legionaries and high-ranking officials were obviously reassigned to different parts of the empire.

There is much more to the story however. If we look at another corner of the empire, more to the east, we see some really fascinating insights into the genetic legacy of the Roman Empire and how it changed the genetics of certain areas. Genetic research has been done in the Balkans for instance, particularly in modern-day Serbia, around a major Roman city and stronghold that was established in the first century AD called Viminacium, which is near the modern town of Kostolac. Viminacium was the capital of the Roman Province of Moesia in the Balkans, which sat just south of the Danube River, a natural barrier for the Romans.
