For many millennia the ancient Greeks call the Thracians "telasokrati" -the sea masters of the world. One of the first collisions they have is in the 60s of the XIII c. B.C. during the Trojan War. The Thracian warriors lead by the legendary king Resos were fighting on the side of the Trojans, which were their kin. The other Thracian tribes were on the side of the Persian king Darius I with whom they battled in 493-492 with the Macedonian king Philip II who attacked them in the middle of IV c. B.C. In 335 his son Alexander the Macedonian continued the war.
