The Battle of Pydna took place in 168 BC between Rome and Macedon during the Third Macedonian War. The battle saw the further ascendancy of Rome in the Hellenistic world and the end of the Antigonid line of kings, whose power traced back to Alexander the Great's Diadochi Antigonus Monophthalmus. The battle is also considered to be a victory of the Roman legion's manipular system's flexibility over the Antigonid Macedonian phalanx's rigidity.
