The Thracians were an Indo-European speaking people who inhabited large parts of Southeast Europe in ancient history. Thracians resided mainly in Southeast Europe in modern-day Bulgaria, Romania and northern Greece, but also in north-western Anatolia in Turkey.
Several Thracian graves or tombstones have the name Rufus inscribed on them, meaning “redhead” – a common name given to people with red hair which led to associating the name with slaves when the Romans enslaved this particular group. Ancient Greek artwork often depicts Thracians as redheads.[84] Rhesus of Thrace, a mythological Thracian king, was so named because of his red hair and is depicted on Greek pottery as having red hair and a red beard. Ancient Greek writers also described the Thracians as red-haired. A fragment by the Greek poet Xenophanes describes the Thracians as blue-eyed and red haired:
…Men make gods in their own image; those of the Ethiopians are black and snub-nosed, those of the Thracians have blue eyes and red hair.
