A criminal organization that originated in Sicily and was brought to the United States by Italian immigrants in the late nineteenth century. The Mafia is also called the Syndicate, the Mob, and the Cosa Nostra (Our Thing). The Mafia built its power through extortion (forcing tradesmen and shopkeepers to buy Mafia protection against destruction) and by dominating the bootlegging industry (the illegal production and distribution of liquor) during Prohibition. Members of the Mafia often lead outwardly respectable lives and maintain a variety of legitimate businesses as a front, or cover, for their criminal activities, which include extortion, gambling, and narcotics distribution.
