Pergamon was a small settlement during the Archaic Period. Lysimachos, one of the generals of Alexander the Great and who had become the sovereign of Anatolia after 301 BC, delivered the war expenditures, at the amount of 9000 talents (1 talent is believed to be US$7,500 approx.), to Philetarios who was the commander of Pergamon, and the kingdom founded by Philetarios by using this sum of money following Lysimachos's death, flourished and became the most eminent center of culture of the Hellenistic period for 150 years. Eumenes I, Attalos I and Eumenes II were enthroned successively after Philetarios. Eumenes II took acropolis of Athens as an example and had the acropolis of Pergamon adorned with works of art which reflected fine taste, and Pergamon became one of the most graceful cities of the world. Attalos III who succeeded Attalos II, handed over his land to the Romans when he died in 133 BC.
