Thracians were regarded by other people as warlike, ferocious, and bloodthirsty. They were seen as "barbarians" by the ancient Greeks and Romans. According to ancient Roman sources, the Dii were responsible for the worst atrocities of the Peloponnesian War killing every living thing, including children and the dogs in Tanagra and Mycalessos. The Thracians would impale Roman heads on their spears and rhomphaias i.e. during the Kallinikos skirmish at 171 BC. Herodotus writes that "they sell their children and let their maidens commerce with whatever men they please"
The Southern part of Thrace was conquered by Philip II of Macedon in the 4th century BC and was ruled by the kingdom of Macedon for a century and a half. Lysimachus of the Diadochi and other Hellenistic rulers ruled part or parts of Thrace until its fall to the Romans.
In 279 BC, Celtic Gauls advanced into Macedonia, Southern Greece and Thrace. They were soon forced out of Macedonia and Southern Greece, but they remained in Thrace until the end of the 3rd century BC. From Thrace, three Celtic tribes advanced into Anatolia and formed a new kingdom called Galatia.
In parts of Moesia (northeast Serbia) the Celtic Scordisci and Thracians lived beside each other, evident in the archaeological findings of pits and treasures, spanning from the 3rd century BC to 1st century BC. During the Macedonian Wars, conflict between Rome and Thracia was inevitable. The ruling parties in Macedonia weakened and Thracian tribal authority resurged. But after the Battle of Pydna in 168 BC, Roman authority over Macedonia seemed inevitable, and the governing of Thracia passed to Rome.
Initially, Thracians and Macedonians revolted against Roman rule. For example, the revolt of Andriscus in 149 BC, drew the bulk of its support from Thracia. Several incursions by local tribes into Macedonia continued for many years, though a few tribes willingly allied with Rome, such as the Deneletae and the Bessi. After the Third Macedonian War, Thracia acknowledged Roman authority.
