Wars of the Successors (323-281 BC)
The Diadochi (plural of Latin Diadochus) were the rival successors of Alexander the Great, and their Wars of the Diadochi followed Alexander's death. This was the beginning of the Hellenistic period of Greek history, the time when many people who were not Greek themselves adopted Greek philosophy and styles, Greek urban life, and aspects of the Greek religion. They are also referred to as Epigonoi.
