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, the closest non-self match for Greek Epirus is Greek Euboea Chalcis (South Euboea Profile). Other nearby references include Greek Central Greece Phocis, Greek Western Greece Aetolia-Acarnania, Albanian Tosk, and Greek Central Macedonia. This gives the Greek Epirus profile its nearest modern genetic context inside the current reference database.

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.
The closest non-self match in this World Genetics comparison is Greek Euboea Chalcis (South Euboea Profile). Other nearby references include Greek Central Greece Phocis, Greek Western Greece Aetolia-Acarnania, Albanian Tosk, and Greek Central Macedonia.
In the current modern G25 reference set, Greek Euboea Chalcis (South Euboea Profile) is the closest listed match to the Greek Epirus average after removing Greek Epirus itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Greek Epirus G25 average, giving the closest-match results a geographic view.
