You think Godfather is a reference to the Italian Mafia.
Think again.
The largely Jewish-American and Italian-American gang known as Murder, Inc. and Jewish mobsters such as Meyer Lansky, Mickey Cohen, Harold "Hooky" Rothman, Dutch Schultz, and Bugsy Siegel developed close ties with and gained significant influence within the Italian-American Mafia, eventually forming a loosely organized, mostly Jewish and Italian criminal syndicate known in the press as the "National Crime Syndicate."
