The Thracian auxiliaries came from modern day Bulgaria after the creation of a province in AD 46. They were used across the empire and in Scotland in 122 AD the Second Cohort of Thracians were based on the Antonine Wall at Mumrills Fort in Polmont as shown in the map below. The Thracians had a very advanced culture with a number of burial mounds holding fabulous objects made from gold. The treasure below is from 300 BC and shows an advanced level of metalwork. Thrace became a tributary (client state) of Rome in 168 BC
In 71 BC Spartacus a Thracian gladiator led a revolt against the Romans
