Campanian (Neapolitan) DNA
Genetic origins and closest populations · Italy · Southern Europe
Naples began as Neapolis, the new city of Greek colonists, and for centuries it was the capital of the Kingdom of Naples, one of the largest states of pre-unification Italy. Campania, around it, was also one of the most densely settled parts of Roman Italy, from Pompeii to the ports of the Bay of Naples. In our model, the Campanian average is 56.5% Anatolian Neolithic farmer, 23.3% steppe, 8.4% Natufian, 7.9% Iranian Neolithic and 3.9% Caucasus hunter-gatherer, a stronger eastern Mediterranean signal than in Apulia (6.9% Natufian, 5.7% Iranian). Ancient DNA from Rome shows large movements of people from the eastern Mediterranean during the Imperial period, and our closest ancient groups fit that picture: Late Antique people with an East Mediterranean profile from Hvar in Croatia (distance 0.0115), early medieval Venosa in Basilicata and Imperial Rome itself. The nearest modern averages are Lucanians from Basilicata (0.0083), Apulians, Calabrians and western Sicilians.
- Largest ancient components in our model: Anatolian Neolithic farmers 56.5%, Steppe herders (Yamnaya) 23.3%, Natufian hunter-gatherers (Levant) 8.4%
- Closest modern population in our data: Italian (Basilicata, Lucanian), distance 0.0083
- Closest ancient group in our data: Croatia Late Antiquity Hvar Radosevic (East Med Profile), distance 0.0115
This page sums up what the DNA of the Campanian (Neapolitan) sample tells us about deep origins. It is built from the averaged Global25 (G25) coordinates of individuals sampled in Italy, listed in the G25 sheet as "Italian_Campania", and it is one of 335 populations in our atlas. An average describes the group as a whole, not any single person in it.
Ancient make-up of the Campanian (Neapolitan) average
In a model built from deep ancestral reference populations, the largest share of the Campanian (Neapolitan) average, 56.5%, goes to Anatolian Neolithic farmers, ahead of Steppe herders (Yamnaya) (23.3%) and Natufian hunter-gatherers (Levant) (8.4%). The Anatolian Neolithic farmers component reflects the Neolithic farmers of Anatolia, who carried agriculture into Europe from about 6500 BC. The Steppe herders (Yamnaya) share (23.3%) reflects the Bronze Age herders of the Pontic-Caspian steppe (Yamnaya and related groups), whose ancestry spread across Europe and into Asia from about 3000 BC.
Smaller traces of Caucasus hunter-gatherers (under 5%) also appear. At that level they can reflect real minor ancestry, but also simple model noise, so they should not be over-read. The model fits well (fit distance 0.016), so these proportions are a reasonable summary. The model draws on West Eurasian ancient genomes, with modern West African and East Asian stand-ins.

Closest modern populations to Campanian (Neapolitan)
Ranking every modern population by genetic distance puts Italian (Basilicata, Lucanian) first for Campanian (Neapolitan), at 0.008, then Apulian and Calabrian. Leaving aside the other regional samples listed under the same name in the G25 sheet, the nearest other populations are Apulian (0.009), Calabrian (0.009) and Greek (Deep Mani) (0.013). Even the tenth closest, Cretan, is only 0.018 away: Campanian (Neapolitan) belongs to a dense cluster of related populations, so small differences inside that cluster should not be over-interpreted.

Distances are Euclidean distances between averaged G25 coordinates. On our scale, below 0.025 is very close, below 0.050 close, below 0.080 moderate, and beyond that distant.
Closest ancient populations to Campanian (Neapolitan)
If we search ancient DNA for the best match to Campanian (Neapolitan), Croatia Late Antiquity Hvar Radosevic (East Med Profile) (Late Antiquity, c. 250-600 AD) comes first, at 0.012, with Italy Basilicata Early Medieval Venosa (East Med Profile) next. That is a very close match, which suggests strong genetic continuity between those ancient people (or close relatives of theirs) and the modern population. A close ancient match is not proof of direct descent: it means those individuals carried a similar overall mix of ancestry.

Ancient DNA from Italy
Our ancient DNA database holds 1,616 individuals excavated in present-day Italy, dated from about 37,855 BC to 1750 AD. The most frequent Y-DNA haplogroups among them are R1b (216), G2a (154) and I2a (59), and the most frequent mtDNA haplogroups are T2 (156), H1 (128) and U5 (121). These are people who lived on the same land in the past, not necessarily ancestors of today's Campanian (Neapolitan) population.

About these numbers
Keep in mind that a population average is a statistical summary of a limited number of sampled individuals. Real people inside any group vary, some carry more of one ancestry and some less, and no genetic profile decides who is or is not Campanian (Neapolitan). Use these numbers as a map of deep ancestry, not as a label.
Method: averaged G25 coordinates, Euclidean distances to other modern and ancient averages, and a non-negative least-squares model against deep ancestral reference populations (data generated 2026-10-01). Read the full method.
