The Sicilian Mafia, also known as Cosa Nostra ("Our Thing"), is a criminal syndicate in Sicily, Italy. It is a loose association of criminal groups that share a common organizational structure and code of conduct. Each group, known as a "family", "clan", or "cosca", claims sovereignty over a territory, usually a town or village or a neighbourhood (borgata) of a larger city, in which it operates its rackets. Its members call themselves "men of honour", although the public often refers to them as "mafiosi". The Mafia's core activities are protection racketeering, the arbitration of disputes between criminals, and the organizing and oversight of illegal agreements and transactions.
