Attalid Dynasty


The Attalid Dynasty ruled an empire from their capital at Pergamon during the 3rd and 2nd centuries BCE. Fighting for their place in the turbulent world following the death of Alexander the Great, the Attalids briefly flourished with Pergamon becoming a great Hellenistic city famed for its culture, library, and Great Altar. However, the Attalids' short-lived dynasty came to an abrupt end when mighty Rome began to flex its muscles and show greater ambition in Asia Minor and beyond.
