Complete chronology

Full overview and deeper context for every journey step.

334-323 BC

Alexander's officer

Perdiccas rose within the Macedonian command structure during Alexander's campaigns. Like other senior officers, he gained authority through battlefield service, proximity to the king, and command over troops who had marched from Macedon to the edges of India. His standing mattered in 323 BC because Alexander's empire had no settled rules for succession. Men like Perdiccas were not simply generals anymore; they were the people who controlled armies, treasuries, and access to the royal family.

In a conquest empire, military rank could become political power almost overnight.

323 BC

Regent after Babylon

Alexander died in Babylon in 323 BC without an adult heir. The settlement that followed tried to preserve unity by naming Alexander's half-brother Philip III Arrhidaeus and unborn son Alexander IV as kings. Real power, however, fell to senior commanders. Perdiccas emerged as regent, a position that made him guardian of the royal authority but also the chief obstacle to every general who wanted independent control of a province.

A compromise succession can create the appearance of order while loading conflict into the future.

322-321 BC

Against the Successors

Perdiccas's regency depended on convincing other generals that the empire still had a center. That was increasingly unrealistic. Ptolemy secured Egypt and seized Alexander's body, turning the dead king into a symbol of legitimacy for his own regime. Antigonus, Antipater, and others also resisted any arrangement that made them subordinate. Perdiccas had authority in theory, but the Successors had armies and territory in practice.

Authority without enough trust or force becomes a title other people test.

320 BC

Failure in Egypt

Perdiccas's campaign against Egypt exposed the weakness of his position. Crossing into Ptolemy's territory was difficult, and failed operations near the Nile damaged morale. His officers lost confidence and murdered him in 320 BC. His death removed the strongest advocate of imperial unity and accelerated the fragmentation of Alexander's empire. After Perdiccas, the Successor wars became openly about rival kingdoms rather than preserving one empire.

When a leader's claim rests on success, one failed campaign can become fatal.
