MyImperial Roman Ancestry: What It Means
"Imperial Roman" is one of the four era-based categories in MyHeritage's Ancient Origins breakdown, and it's also one of the more surprising ones — because Rome, at the height of its empire, was genetically one of the most cosmopolitan cities of the ancient world.
| Also called | Roman-era ancestry, Imperial Rome ancestry |
|---|---|
| Time period | Roughly 27 BCE – 476 CE (the Roman Empire, at its height stretching from Britain to Egypt) |
| Key finding | Ancient Rome's population was highly diverse, shifting substantially over time |
| Key study | Antonio et al., "Ancient Rome: A genetic crossroads of Europe and the Mediterranean" (Science, 2019) |
| Modern relevance | A cultural and political category as much as a fixed genetic one |
Who were the Imperial Romans?
At its peak, the Roman Empire spanned three continents, connecting Britain, North Africa, the Levant, and everything in between through trade, military movement, and administration. A widely cited 2019 study in the journal Science analyzed ancient genomes from around 127 individuals spanning some 12,000 years of Rome's history and found that the city's population during the Imperial period was extraordinarily diverse, drawing significant ancestry from the Eastern Mediterranean and Near East — a genetic reflection of Rome's role as the administrative and economic center of a vast, interconnected empire. That diversity later shifted again in Late Antiquity and the early medieval period, as the population moved toward ancestry more typical of Western Europe following the empire's political fragmentation.
How Roman-era ancestry shows up in modern populations
Because "Roman" describes a political and cultural identity that stretched across an enormous and genetically varied territory, Roman-era ancestry in a modern DNA result doesn't point to one specific region the way, say, Scandinavian ancestry might. It can reflect descent from populations anywhere the empire's cosmopolitan networks reached — Italy, the Balkans, Anatolia, the Levant, North Africa, or Western Europe — during the centuries the empire was at its height. This makes it one of the broadest and most historically layered categories in an ancient-origins breakdown.
If your Ancient Origins results show Roman-era ancestry
A Roman-era result means your DNA resembles reference samples dated to the Imperial period, drawn from the empire's genetically mixed population centers. It doesn't necessarily mean documented Italian descent — given how mobile and diverse the empire's population was, this category can appear across a wide range of modern European and Mediterranean ancestries.

Roman-era ancestry vs. Iron Age Celtic ancestry
These two categories sit on either side of one of history's most consequential frontiers. Iron Age Celtic ancestry represents the Celtic-speaking populations of pre-Roman Western and Central Europe, many of which were later absorbed into, or lived alongside, the expanding Roman Empire. A person's results might show both — reflecting ancestry from populations with roots in pre-Roman Iron Age Europe as well as ancestry shaped by centuries of life within (or trade with) the Roman world.
Does Roman-era ancestry mean I'm descended from Italians specifically?
Not necessarily. Because the Roman Empire's population — especially in the city of Rome itself during the Imperial period — was drawn from across the Mediterranean and Near East, a Roman-era signal can reflect ancestry from many different regions the empire once encompassed, not just the Italian peninsula.
Why was ancient Rome so genetically diverse?
Rome was the political, economic, and administrative hub of an empire spanning three continents. Trade, military postings, slavery, and migration for opportunity all brought people from across the empire's vast territory into the city, making its population unusually cosmopolitan for the ancient world — a pattern confirmed by ancient-DNA studies of Roman-era burials.
