Ptolemy I

Macedonian general (367–283 BCE) who secured Egypt after Alexander's death, founded the Ptolemaic dynasty, and established Alexandria as the world's center of learning, creating the most successful of the Diadochi successor states.

When Alexander the Great died in 323 BCE, his generals immediately fought to carve up the empire, the Diadochi Wars. Ptolemy made the most strategically brilliant single move: he seized Alexander's body as it was being transported to Macedonia and buried it in Alexandria. Possession of the conqueror's tomb conferred a legitimacy that no military victory could provide.

His choice of Egypt was equally brilliant. Egypt was the Mediterranean's most defensible and most productive territory, protected by deserts, watered by the Nile, generating enormous grain surpluses that could fund armies and purchase allies.

His greatest legacy was the Library of Alexandria, an attempt to collect every book in the world, staffed by the greatest scholars of the Hellenistic era. This was not pure altruism; knowledge accumulation was power projection. The Library made Alexandria the intellectual capital of the ancient world for three centuries.
