About Lysistrata (from Wikipedia):
Lysistrata is a comedy by Aristophanes. Originally performed in classical Athens in 411 BCE, it is a comic account of a woman’s extraordinary mission to end the Peloponnesian War by denying all the men of the land any sex, which was the only thing they truly and deeply desired. Lysistrata persuades 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 being an early exposé of sexual relations in a male-dominated society. Additionally, its dramatic structure represents a shift from the conventions of Old Comedy, a trend typical of the author’s career.
