Abroi
The Abroi were an Illyrian tribe. They may have been a constituent northern tribe of the larger group of the Taulantii, on the Adriatic coast of southern Illyria.
Name
The tribe is mentioned solely by Hecataeus of Miletus, in fragment 69 of Periodos ges, cited by Stephanus of Byzantium. The name of the tribe is recorded in Ancient Greek as Ἄβροι Abroi.Their name may have actually been Arboi as Abroi may have been produced via a metathesis, another linguistic process or a common misassociation by Hecataeus of their name with the ancient Greek term abros to better adapt it to Greek. The name Arboi would link them to the Illyrian Albanoi, who are attested in the same area in the 2nd century CE.
N. G. L. Hammond has pointed out that the name Abroi and Albanoi gave rise to the name Albania/Albanians, similar to the spread of the name Illyria/Illyrians from a small group of people on the Adriatic coast, the Illyrioi. This process can also be seen in the case of Graeci and Hellenes.
