Capo dei capi (Italian: [ˈkaːpo dei ˈkaːpi]; "boss of [the] bosses"), capo di tutti i capi (Italian: [ˈkaːpo di ˈtutti i ˈkaːpi]; "boss of all [the] bosses") or Godfather (Italian: padrino) are terms used mainly by the media, public, fiction writers and law enforcement community to indicate a supremely powerful crime boss in the Sicilian or American Mafia who holds great influence over the whole organization. The term was introduced to the U.S. public by the Kefauver Commission in 1950.[1]
