An international secret society originating in Sicily. In its modern form the Mafia (Italian ‘boldness’) can be said to date from the period 1806–15, when, under British pressure, attempts were being made to break up the huge estates of the Sicilian feudal aristocracy. In the 1880s many Sicilians emigrated to the USA and the Mafia, as Cosa Nostra (Our Business), became established in New York and Chicago. In the 1920s the fascist government in Italy brought Mafia leaders to trial, but some escaped to the USA, where they were active during the Prohibition era. After World War II, notably after the opening-up of the former Soviet bloc, Mafia activities spread worldwide, increasingly centred on the drug trade. The Mafia is also involved in organized prostitution, fraud, theft, and kidnapping. In the USA, the Mafia is notable also for its infiltration of legitimate business—for example, in transport, construction, gambling, and fast-food—and its use of these businesses for money-laundering. Mafia members are required to live by a code of silence and eschew all cooperation with legitimate authorities: any violation of this code is severely punished.
