Argead dynasty
Defenders of the Argead dynasty began to declare that Alexander IV, at the age of 14, should now rule on his own and that a regent was no longer needed. Cassander realized that to secure his rule Alexander would need to be removed, and in 309 BC he commanded Glaucias to assassinate the Alexander IV and his mother. The orders were carried out, and they were both poisoned. The consensus in "A History of Macedonia Vol. 3" is that Alexander was killed late in the summer of 309 BC, shortly after his alleged half-brother Heracles.
