Agreement between two or more persons to commit an unlawful act or to accomplish a lawful end by unlawful means. Some U.S. states require an overt act in addition to the agreement to constitute conspiracy. Individual conspirators need not even know of the existence or the identity of all other conspirators. In a chain conspiracy the parties act separately and successively (as in distributing narcotics). A civil conspiracy is not prosecuted as a crime but forms the grounds for a lawsuit. In antitrust law, conspiracies in restraint of trade (e.g., price fixing) are rigorously prosecuted. In the U.S. it is common to punish a conspiracy to commit an offense more harshly than the offense itself, but there has been a growing trend to follow the European example and make the punishment for conspiracy the same as or less than that for the offense itself.

(April 16, 1478) Unsuccessful plot to overthrow the Medici rulers of Florence. It was led by the rival Pazzi family, with the backing of Pope Sixtus IV, who wanted to consolidate papal rule over northern central Italy. The conspirators tried to assassinate two Medici brothers during mass at the Cathedral of Florence; they killed Giuliano de' Medici, but Lorenzo de' Medici escaped. The people of Florence rallied to the Medici and killed many of the conspirators, leaving Lorenzo more powerful than before and setting off a two-year war with the papacy.
