The Chicago outfit is an Italian-American Crime family in Chicago, Illinois. They started up in 1910 and have been around ever since, even today. Johnny Torrio was in control of the outfit when they rose to power in 1920. They had bloody gang wars for distribution of illegal alcohol during prohibition. Tony Accardo became the outfits boss many years later and ran it all the way up into the 1990s when he died. That made him the longest running boss in mob history. They are still active today and are still involved in some crimes.
