Editing Cassander (section)

==Early history==
In his youth, Cassander was taught by the philosopher [[Aristotle]] at the [[Lyceum]] in [[Macedonia (ancient kingdom)|Macedonia]]. He was educated alongside [[Alexander the Great]] in a group that included [[Hephaestion]], [[Ptolemy I of Egypt|Ptolemy]] and [[Lysimachus]].<ref name="Heckel, p.153">Heckel, ''Who's who in the age of Alexander the Great: prosopography of Alexander's empire'', p. 153</ref> His family were distant collateral relatives to the [[Argead dynasty]].<ref>[http://www.tyndalehouse.com/egypt/ptolemies/affilates/aff_ptolemies.htm Ptolemaic Dynasty - Affiliated Lines: The Antipatrids] {{webarchive |url=https://web.archive.org/web/20110716100716/http://www.tyndalehouse.com/egypt/ptolemies/affilates/aff_ptolemies.htm |date=July 16, 2011 }}</ref>

Cassander is first recorded as arriving at Alexander the Great's court in [[Babylon]] in 323 BC, where he had been sent by his father, [[Antipater]], most likely to help uphold Antipater's regency in Macedon, although a later contemporary who was hostile to the Antipatrids suggested that Cassander had journeyed to the court to poison the King.<ref name="fox469">Fox, Robin Lane.
