Alcibiades, the Defector
He woke up as an Athenian general — by nightfall, he was plotting with Athens’ deadliest enemies.

From hero to traitor overnight.
Alcibiades was the golden boy of Athens: handsome, clever, dangerously persuasive. Accused of sacrilege on the eve of Sicily’s invasion, he fled instead of standing trial — and was welcomed by the Spartans, Athens’ most hated rivals.
Outwitting three empires.
Later, Alcibiades became a military advisor to Sparta, famously recommending fortifying Decelea in Attica. But his enemies there turned on him too, and he defected again — this time, to the Persian satrap Tissaphernes. Each move kept him alive and influential.
Did he ever come home?
He did return to Athens eventually, cheered as a savior after orchestrating key victories. But Athenian politics were unforgiving. Exiled yet again, Alcibiades died in obscure circumstances, a reminder of how charisma and ambition couldn’t outweigh shifting alliances.
Alcibiades switched allegiances not once, but three times during the Peloponnesian War. He fought for Athens, then for Sparta, then for Persia, manipulating each for his own survival — and glory.
