Alexandropolis in the Thracian region of Maedians, was the first town founded by Alexander the Great after he defeated a local Thracian tribe as a regent of Macedon in 340 BC. Its name was chosen by analogy with Philippopolis, the town of Thrace founded by Alexander's father, Philip II. He expelled the locals and settled a mixed population. The location of Alexandropolis is unknown, suggesting that a Thracian raid may have caused its disappearance from history. Tarn claims Alexandropolis was a military colony rather than a polis.
