It is thought that the Greek dynasts of Pergamon were punished following the Peace of Antalcidas in 386 BCE for their support of the Greeks against the Achaemenids. However, by the mid-4th century BCE, the Achaemenid satrap Orontes again allowed the people of Pergamon to settle on the acropolis of their city. This lasted until the conquests of Alexander the Great, when Pergamon became part of the Macedonian Empire.
