It is a loose association of criminal groups that share a common organisational structure and code of conduct, and present themselves to the public under a common brand. The basic group is known as a "family", "clan", or cosca Each family claims sovereignty over a territory, usually a town or village or a neighbourhood 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. By the 20th century, following wide-scale emigration from Sicily, mafiosi established gangs in North and South America which replicate the traditions and methods of their Sicilian ancestors.
