Attalid dynasty
It was one of four dynasties established by Alexander's successors, the others being the Seleucid dynasty, Ptolemaic dynasty and Attalid dynasty. The last scion of the dynasty, Perseus of Macedon, who reigned between 179 and 168 BC, proved unable to stop the advancing Roman legions and Macedon's defeat at the Battle of Pydna signaled the end of the dynasty.
