(Plin. HN 3,147; Suet. Tib. 9,2; Str. 7,5,3; Ptol. 2,15,3: Βρεῦκοι; Breûkoi). Illyrian tribe, settling in Pannonia Inferior along the lower reaches of the Save, subjugated by the Romans between 12 and 10 BC; the B. took part in the Pannonian revolt of AD 6 to 9. From then on, the B. were recruited as Roman auxiliaries -- eight cohortes Breucorum are attested for the imperial period.
