Eleven Years, No Plan B
In 334 BCE, a twenty-two-year-old crossed into Asia with 40,000 men. Eleven years later, he had destroyed the Persian Empire, marched from the Nile to the Indus, and died in Babylon at thirty-two.
On his deathbed, when asked who should inherit his vast realm, he reportedly gave one word: "to the strongest."
Alexander had built a conquest, not a state: no heir, no succession rule, and no administrative class. The empire was held together by one thing, and that thing was now dead.
The Carve-Up and the Hellenistic World
His generals, the Diadochi ("successors"), fought for forty years until the battle of Ipsus (301 BCE) fractured the realm into three spear-won monarchies (rule by right of conquest, bureaucracy, and ruler cults):
| Kingdom | Founder | Heartland |
|---|---|---|
| Ptolemaic | Ptolemy | Egypt, richest |
| Seleucid | Seleucus | Mesopotamia to Iran |
| Antigonid | Antigonus' line | Macedon and Greece |
Greek political freedom died, but culture conquered. Koine Greek became the global working language. Cities like Ai-Khanoum in Afghanistan mirrored Athens, while Alexandria housed the legendary Library and Museum where Euclid and Eratosthenes revolutionized science.
