Athenian Demagogue and General
"A democracy is incapable of empire."
Cleon was Athens's most powerful politician after Pericles' death — and everything Pericles was not. A tanner's son who made his fortune in trade, he rose to leadership through inflammatory popular oratory, personal attacks on opponents, and a willingness to make democratic assemblies vote for the most brutal options available. Thucydides, who despised him, is our main source — and even Thucydides admits that Cleon's most unpopular policies sometimes worked. His greatest triumph was the capture of the Spartan hoplites at Sphacteria in 425 BC — a coup he had boasted was easy and then delivered on, shaming the generals who doubted him. With 120 full Spartiate prisoners in Athenian hands, Cleon wielded extraordinary leverage and probably could have negotiated a favourable peace at the moment of Athens's greatest strength. He refused, preferring to continue the war toward total victory. His death at Amphipolis in 422 BC — killed while fleeing when Brasidas's surprise sortie routed his force — was almost comically humiliating for a man who had presented himself as the people's warrior. Yet his death, combined with Brasidas's death in the same battle, removed both sides' war hawks and opened the Peace of Nicias. The man who prevented peace for years died simultaneously with his opposite number, making peace possible at last.
Did you know?
Cleon famously promised the Athenian assembly that if given command, he would bring back the Spartan prisoners from Sphacteria within 20 days — an insane boast. He did it in 20 days exactly, making him briefly the most admired man in Athens and permanently embarrassing the generals he had shamed.
425 BC · 600 total casualties
The capture of 120 full Spartiates devastated Sparta's prestige and gave Athens enormous negotiating leverage. Sparta had previously raided Attica every summer; now Athens threatened to kill the prisoners if raids continued. The victory made Cleon the most powerful man in Athens and seemed, briefly, to promise an Athenian win.
422 BC · 1,600 total casualties
The deaths of Cleon and Brasidas — the two men most hostile to peace — cleared the way for the Peace of Nicias (421 BC), a nominal fifty-year truce that actually solved nothing. Their removal illustrates how individual personalities shaped the pace and character of the war.
