Third Macedonian War
Amid these alliances, Abrupolis, the king of the Thracian tribe of the Sapaei and an ally of the Romans attacked Macedon, laid it waste as far as Amphipolis, and overran the gold mines of Mount Pangaeus. He was repulsed and then driven out of his territories by Perseus. This conflict contributed to the tensions which led to the Third Macedonian War, because Rome took issue with the ousting of its ally.
