The war marked the end of Greek political independence, and the beginning of the end of the Hellenistic period. Pergamon, the only significant remaining power in the Aegean, was generally pro-Roman, and its last king, Attalus III, bequeathed it to Rome through his will upon his death in 133 BC. Thus, seventy years after Rome was first involved in Greek affairs in the First Macedonian War, it was now in control of all of the classical Greek world, and had cemented its position as the dominant power in the Mediterranean.
