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 B.C., 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
