Mafia

Informally or generally, a mafia is any of various criminal organizations that include, or bear a strong similarity to, the original Sicilian Mafia, the Italian-American Mafia, or other Italian organized crime groups. 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 violence. Mafias often engage in secondary activities such as gambling, loan sharking, drug trafficking, prostitution, and fraud.
