Cleon (died 422 bc, Amphipolis, Macedonia) was the first prominent representative of the commercial class in Athenian politics, he became leader of the Athenian democracy in 429 after the death of his political enemy, Pericles. In the Peloponnesian War he strongly advocated an offensive strategy. When Mytilene, which had revolted against Athens, fell in 427, Cleon proposed that all its citizens be put to death and the women and children enslaved. His decree was passed but rescinded the next day, in time to save Mytilene. He reached the summit of his fame by capturing the Spartans on the besieged island of Sphacteria in 425 after refusing their peace terms, but was defeated and killed at Amphipolis by the Spartan general Brasidas when trying to recover the cities of Thrace for the Athenian Empire. Cleon is represented by Aristophanes and Thucydides in an extremely unfavourable light, but neither can be considered an unprejudiced witness.
