241 BCE
Pergamon, originally a mountain fortress on the Aegean coast, has become an important continental power through the careful maneuvering of its rulers, Philetaerus (282-263) and later his nephew Eumenes (263-241).
Attalus, whose mother, Antiochis, is a princess of the Seleucid house, in 241 succeeds his uncle Eumenes.
