The Macedon was the mainly low lands around modern Thessaloniki. Under Alexander Macedon took firm control of the upper Macedonian regions up to Lake Ochrid which were inhabited by both Greek tribes and indigenous peoples. This area roughly covers that of modern Greek Macedonia. He further extended control of non-Macedon states of Paeonians and Thracians and continued to create the Macedonian Empire (359 - 336) nominally reaching and crossing the Danube, but failed to subdue the Dacians.
The Dacians were developing their their iron, silver and gold from the Transylvanian mines and soon began trading with the Greeks. Following Dromihetes successes against Alexander the Great, Burebista's reign formed a large Dacian state that probably extended beyond the current Romanian boundaries.
