Ptolemy of Aloros (Ancient Greek: Πτολεμαῖος), was sent by King Amyntas III of Macedon as an envoy to Athens c. 375–373 BC.
[1] In 368 BC, he assassinated her son, Alexander II, in order to gain control of the throne.
[2][3] His actions were not well-regarded by the leading families of Macedon, who called in the Theban general, Pelopidas, to re-establish peace.
As part of the peace settlement, Philip, Alexander II's younger brother, was taken as a hostage back to Thebes.
It is suggested that Ptolemy was descended from Amyntas II's brother, Menelaus, son of Alexander I.
