Mafia
A mafia is a type of organized crime syndicate whose primary activities are protection racketeering, arbitrating disputes between criminals, and brokering and enforcing illegal agreements and transactions. Mafias often engage in secondary activities such as gambling, loan sharking, drug-trafficking, prostitution, and fraud. Nowadays the 'Ndrangheta, originating in the southern Italian region of Calabria, is widely considered the richest and most powerful mafia in the world. The term "mafia" was originally applied only to the Sicilian Mafia and originates in Sicily, but it has since expanded to encompass other organizations of similar methods and purpose, e.g., "the Russian Mafia" or "the Japanese Mafia". The term is applied informally by the press and public; the criminal organizations themselves have their own terms.
