Lysistrata is one of the few surviving plays written by Aristophanes. Originally performed in classical Athens in 411 BC, it is a comic account of one woman's extraordinary mission to end The Peloponnesian War. Lysistrata convinces the women of Greece to withhold sexual privileges from their husbands and lovers as a means of forcing the men to negotiate peace, a strategy however that inflames the battle between the sexes. The play is notable for its exposé of sexual relations in a male-dominated society and for its use of both double entendre and explicit obscenities. The dramatic structure represents a shift away from the conventions of Old Comedy, a trend typical of the author's career. It was produced in the same year as Thesmophoriazusae, another play with a focus on gender-based issues, just two years after Athens' catastrophic defeat in the Sicilian Expedition.
