The Wars of Alexander's Successors

Alexander died at thirty-two with no adult heir, no named successor, and an empire stretching to India. His generals spent forty years killing each other and everyone with a claim: his wife, his mother, his half-brother, and his posthumous son were all murdered, ending his bloodline entirely. Three kingdoms emerged — Macedonian Greece, Seleucid Persia, Ptolemaic Egypt — and spent two centuries fighting until Rome absorbed them one by one. An empire assembled in a decade by one man dissolved in a generation because he never answered the only question that mattered.
