The American Italian Anti-Defamation League was a political advocacy group formed by a group of Italian Americans from New York City in 1967. It held a concert in New York City at which Frank Sinatra, the national chairman, sang for an audience of 20,000. The group's ostensible purpose was to prevent Italian Americans as a group from being defamed, primarily by being uniformly stereotyped as all being involved with or related to persons or activities associated with the Mafia.
