A focused population profile of Greeks from Epirus, their northwestern Greek background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Greeks from Epirus are associated with northwestern Greece, including Ioannina, Arta, Preveza, Thesprotia, and the Pindus mountain region. Epirote history includes ancient Greek tribal societies, Roman and Byzantine periods, Ottoman-era Ioannina, mountain villages, pastoral networks, and long interaction with Albania, western Macedonia, Thessaly, and western Greece.
Greek is the main language, with regional Epirote speech and local identities. Epirus should be read as a northwestern mainland Greek profile, not as an island Greek or southern Peloponnesian average.
As a genetic reference, Greek Epirus is useful for comparison with Central Greece, Central Macedonia, Phocis, Thessaly, Aetolia-Acarnania, Albanian Tosk, Western Macedonia, Greek Macedonia, and other Balkan Greek references.
In the World Genetics modern G25 comparison, Greek Epirus is closest to Greek Central Greece Boeotia, Greek Central Macedonia, Greek Central Greece Phocis, Greek Thessaly, Greek Euboea Psachna, Greek Western Greece Aetolia-Acarnania, Albanian Tosk, Greek Euboea Chalcis with a South Euboea profile, Greek Western Macedonia, and Greek Macedonia. The result places Epirus in a mainland Greek and western Balkan-adjacent cluster.
| Population | Distance |
|---|
The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Epirote Greek is best interpreted as a northwestern mainland Greek profile, close to central Greek, Macedonian Greek, Thessalian, western Greek, and Albanian Tosk references.
The heatmap should emphasize Epirus, northwestern Greece, Central Macedonia, Thessaly, Boeotia, Phocis, western Greece, southern Albania, and western Macedonia.
Yes. Greek Epirus sits close to central Greek, Macedonian Greek, Thessalian, western Greek, and Euboean references.
Albanian Tosk appears among the closest matches, reflecting broader northwestern Greek and southern Balkan overlap.
Yes. Greek Central Macedonia, Greek Western Macedonia, and Greek Macedonia appear close to Greek Epirus.
