The Diadochi and the Successor Kingdoms “Whether, had he lived longer, Alexander could have organized and co-ordinated this inchoate area effectively is a moot question. Without him even the survival as a whole seemed unlikely. The history…from 323 to 301 is of a struggle between Alexander’s generals to take what they could for themselves.” F.W. Walbank, The Hellenistic World

Aftermath of Alexander’s Death: The Question of the Succession  Internal Disputes and Near Civil War Perdiccas and cavalry support the unborn child of Roxane (Alexander IV) Meleager and infantry support Philip II’s bastard son Arrhidaeus (Philip III)  Joint Successors, Alexander IV and Philip III as puppets of the generals

The Diadochi’s (Successors’) Struggles for Supremacy  The Principal Players: Perdiccas (senior cavalry officer); Ptolemy and Leonatus (related to Argeads); Meleager (senior infantry officer); Peucestas (satrap of Persis and Susiana); Lysimachus (Alexander’s confidant); Seleucus (commander of hypaspists); Eumenes of Cardia (court secretary); Antipater (regent in Macedonia); Cassander (son of Antipater); Craterus; Antigonus (satrap of Phrygia)  Perdiccas’ failed attempt at reconciliation and unity ( BCE) Perdiccas murdered in Egypt in 320 BCE Settlement at Triparadeisis in northern Syria in 320 BCE = Antipater in Macedonia and Greece; Antigonus in Asia; Seleucus in Syria; Ptolemy in Egypt The Settlement of 311 BCE: Cassander regent in Europe; Lysimachus controls Thrace; Ptolemy in Egypt; Antigonus controls Asia

On the Settlement of 311 BCE “When Simonides was archon at Athens, the Romans elected to the consulship Marcus Valerius and Publius Decius. While these held office, Cassander, Ptolemy, and Lysimachus came to terms with Antigonus and made a treaty. In this it was provided that Cassander be general of Europe until Alexander, son of Roxane, should come of age; that Lysimachus rule Thrace, and that Ptolemy rule Egypt and the cities adjacent to it in Libya and Arabia; that Antigonus have first place in all Asia; and that the Greeks be autonomous. However, they did not abide by these agreements but each of them, putting forward plausible excuses, kept seeking to increase his own power.” Diodorus,
