mafia

The "Mafia" is sometimes used as an informal term to describe criminal organizations that bear a strong similarity to the Italian Mafia (Cosa Nostra, 'Ndrangheta and Camorra), the original "Mafia". The central activity of such an organization would be the arbitration of disputes between criminals as well as the organization and enforcement of illicit agreements between criminals through the use of or threat of violence. Mafias often engage in secondary activities such as gambling, loan sharking, drug-trafficking, prostitution, and fraud.

In modern times, 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 (e.g. the Sicilian Mafia and the related Italian-American Mafia refer to their organizations as "Cosa Nostra"; the "Japanese Mafia" calls itself "Ninkyō dantai" but is more commonly known as "Yakuza" by the public; and "Russian Mafia" groups often call themselves "Bratva").
When used alone and without any qualifier, "Mafia" or "the Mafia" typically refers to either the Sicilian Mafia or the Italian-American Mafia and sometimes Italian organized crime in general (e.g., Camorra, 'Ndrangheta, etc.).
