• History of Demetrias

Demetrias (Ancient Greek: Δημητριάς) was an ancient Greek city in Magnesia (east central Greece), near the modern city of Volos. It was founded by Demetrius Poliorcetes, and became the favourite residence of the kings of Macedon.

In 196 B.C., the Romans, victorious in the battle of Cynoscephalae over Philip V of Macedon in the previous year, took possession of Demetrias, but four years later the Aetolian League captured it by surprise. The Aetolians allied themselves with Antiochus III of the Seleucid Empire in the Roman–Syrian War. This ended in the defeat of Antiochus. The Romans then returned Demetrias to Philip, who had been their ally in this war. It remained a Macedonian possession until the battle of Pydna in 169 B.C.
