Rudolph William Louis Giuliani is an American politician and lawyer who served as the 107th mayor of New York City from 1994 to 2001. He previously served as the United States Associate Attorney General from 1981 to 1983 and the United States Attorney for the Southern District of New York from 1983 to 1989.

The Mafia Commission Trial was a criminal trial before the United States District Court for the Southern District of New York in New York City, United States, that lasted from February 25, 1985, until November 19, 1986. Using evidence obtained by the Federal Bureau of Investigation, 11 organized crime figures, including the heads of New York City's "Five Families", were indicted by United States Attorney Rudolph Giuliani under the Racketeer Influenced and Corrupt Organizations Act (RICO) on charges including extortion, labor racketeering, and murder. Eight of them were convicted under RICO, and most were sentenced to 100 years in prison on January 13, 1987, the maximum possible sentence under that law.
