Pergamon — A settlement in Mysia also known as Pergamum - Pergamos
Pergamon was a rich and powerful ancient Greek city in Mysia. It is located 26 kilometres (16 mi) from the modern coastline of the Aegean Sea on a promontory on the north side of the river Caicus.

It did not become important until Lysimachus, King of Thrace, took possession in 301 BC, but soon after his lieutenant Philetaerus enlarged the town, the kingdom of Thrace collapsed and it became the capital of the new kingdom of Pergamon which Philetaerus founded in 281 BC.

As a consequence of its rise to power, the city expanded greatly. Until 188 BC, it had not grown significantly since its founding by Philetaerus, and covered c. 21 hectares (52 acres). After this year, a massive new city wall was constructed, 4 kilometres (2.5 mi) long and enclosing an area of approximately 90 hectares (220 acres).

When Attalus III (138–133 BC) died without an heir in 133 BC, he bequeathed the whole of Pergamon to Rome in order to prevent a civil war. It reached the height of its greatness under Roman Imperial rule and was home to about 200,000 inhabitants.
