Who were the Illyrian (1200 – 250 BC)?

Illyrian is one of the 27 curated source populations in the Classical Antiquity era of the Ancestrify qpAdm analysis: a group of published ancient genomes from one archaeological context, pooled as a single reference the model can test your genome against.

Does Illyrian in my result mean they were my ancestors?

No. A source population is a reference the model tests against, never a statement about who your ancestors were. A coefficient on this source means the ancestry those burials represent helps explain your genome to within statistical noise — similar ancestry composition, not descent from those individuals. Ancestrify never claims a population is your ancestor.

What does a Illyrian percentage in a qpAdm model mean?

qpAdm estimates the mixture proportions that best explain your genome as a combination of the chosen sources, given a fixed set of outgroup (right) populations, and reports a p-value for whether the model is statistically acceptable together with a standard error for every proportion. The percentage is that estimated share, with its uncertainty published beside it.

How do I get a qpAdm model that uses Illyrian?

Order the Ancestrify qpAdm analysis (€29.99, one-time) and upload the raw file you already have from a consumer test. Your genome is merged into the AADR reference panel and modelled across both eras; each era's model is built from that era's source populations, so a model for the Classical Antiquity era draws on Illyrian where it improves the fit.

Can I model Illyrian ancestry for free first?

Yes. The Ancestrify Lab runs Global25 admixture calculators, a nearest-populations distance tool and an AdmixTools 2 workbench in your browser with no account, and several calculators cover the Classical Antiquity era. Those are G25 fits, not formal qpAdm models — the paid analysis is the one with a p-value.

Illyrian — ancient DNA source population (qpAdm)

Who they were

Artistic interpretation of the Illyrian (AI-generated artwork, not documentary evidence)

Period: 1200 – 250 BC
Era in the analysis: Classical Antiquity
Region: Western Balkans and Adriatic coast
Role in the model: Source (left) population — a reference qpAdm tests against

The Illyrians were the Bronze and Iron Age peoples of the western Balkans, from the Dalmatian coast and the Dinaric mountains to present-day Albania and Montenegro, known through Greek and Roman writers and their own hillforts and tumulus cemeteries. Ancient genomes from the region show a population combining Neolithic farmer, steppe-related and hunter-gatherer ancestry in Balkan proportions — more farmer than the north, less than the Aegean — that remained largely stable from the Bronze Age until the Roman conquest (Lazaridis et al. 2022; Olalde et al. 2023).

Illyrian-related ancestry is a substantial pre-Slavic layer in present-day Albanians, Croatians, Bosnians, Montenegrins and Serbs, and reaches across the Adriatic into Italy through Roman-era mobility. In the model it sits between the Thracian source to its east and the Latin and Etruscan source across the sea, and it is the closest ancient source to the later Proto Albanian.

In Ancestrify's qpAdm service, Illyrian is a source in the "Classical Antiquity" era. The report shows its weight with a standard error and a Z-score, so you can see not only how much of the model it carries but how confidently that share is separated from zero, and a model that cannot support it is rejected rather than published. For genomes from the western Balkans its weight against the Early Slavic source describes how much of the medieval inflow the model detects, and against the Proto Albanian source how far the two related references could be told apart.

Y haplogroups J2b-L283, R1b-Z2103 and E-V13, and mtDNA H, K, J and T2, are reported from these samples. A haplogroup alone is never evidence of a share.

In your report
An Indo-European-speaking confederation of tribes who inhabited the western Balkans during the Iron Age, occupying territory corresponding to modern Albania, Montenegro, Kosovo, Croatia, Bosnia, and western Serbia. Ancient DNA from Iron Age Balkan individuals reveals a genetic profile combining Neolithic farmer ancestry with Bronze Age steppe-derived contributions, reflecting Illyria's position at the crossroads of Mediterranean and continental European influences. Genomic analysis of over 6,000 ancient Balkan genomes demonstrates that modern Albanians descend in part from Roman-era western Balkan populations with genetic continuity traceable to Bronze Age Illyrians. Paternal lineages including J2b2a1-L283, E-V13, and R1b show pronounced continuity between ancient Illyrian-period and modern Albanian populations. Subsequent Roman imperial, Migration Period, and Slavic demographic changes significantly transformed the broader Balkan genetic landscape while Albanian populations retained substantial Illyrian-related ancestry.

Where this population sits in the model

The Ancestrify qpAdm analysis models your genome once per era. The Classical Antiquity era has 27 curated source populations, and Illyrian is one of them: every candidate model for that era is a combination of these sources, tested against a fixed set of outgroup populations, and only a model that passes the statistical fit check is published — with a p-value, and a standard error on every proportion.

A reference, not a verdict: every population on this page is a source the model tests your genome against — a well-sampled point in ancient genetic space that a mixture of ancestries can be expressed in terms of. A weight on it means your genome is well described as partly resembling those people; it is never a statement that they, specifically, were your ancestors, and a population that fits well is not the only one that could.

Model it yourself for free

The Ancestrify Lab runs in your browser, with no account. Paste a Global25 row into an admixture calculator that covers the Classical Antiquity era, rank the closest ancient populations in the distance tool, or run f4, qpWave and qpAdm on the public panel in the AdmixTools 2 workbench. These are Global25 fits and exploratory statistics, not the formal qpAdm model of the paid analysis.
