The Vicissitudes of the Diadoch Kingdoms: The Final Years of Diodorus’ Persian Account

This chapter falls, in fact, apart in two parts, the first discussing the events, from 310 bc onward, leading up to the Battle of Ipsus (which took place in 301 bc and where Antigonus the One-eyed was killed and Demetrius barely survived) and the battle’s aftermath, the second part discussing the period between c. 280 and c. 64 bc, when the arrival of Pompey formally ended the Seleucid empire, already weakened due to the invasion of the Parthians. In this second part, several Seleucid rulers feature prominently. The end of the Seleucid empire marked the end of Diodorus’ history of Persia. The Ptolemies survived about 30 years longer as rulers before they also formally submitted to Rome: their demise ended the Hellenist kingdoms.
