Alexandrupolis

According to Plutarch's Life of Alexander, Alexandrupolis was the first town that was founded by Alexander, in 340, when he was regent. While his father, king Philip II of Macedonia, was involved in the eastern campaign that culminated in the Perinthus incident, Alexander waged a brief campaign against the rebellious Maedi, a tribe that must have lived somewhere in the southwest of modern Bulgaria.

After he had subdued the rebels, the young prince founded Alexandrupolis, "the town of Alexander". Its location is not known, but the town can not have been far from modern Sandanski.

The fact that we don't know where Alexandrupolis was founded, suggests that it was abandoned or renamed soon after it had come into being. A Thracian raid may have caused its disappearance from history.
