Context: Constantino Paul "Big Paul" Castellano (] ; June 26, 1915 – December 16, 1985), also known as "The Howard Hughes of the Mob" and "Big Paulie" (or "PC" to his family), was an American mafia boss who succeeded Carlo Gambino as head of the Gambino crime family in New York, the nation's largest Cosa Nostra family at the time.  The unsanctioned assassination of Castellano in 1985 by John Gotti sparked years of animosity between the Gambinos and the other New York crime families.

Mazzone's rise in power through the Philadelphia underworld began as a protege of former boss turned informant, Ralph Natale.  After the family was decimated by prosecutions during the Nicodemo Scarfo and John Stanfa eras, Natale was released from prison in 1994 and shortly thereafter became the new boss of the crime family.  Natale partnered with the "Young Turks" faction that was one of the few remnants left of the Philadelphia crime family, and their leader, Joseph "Skinny Joey" Merlino.  After Natale assumed the top position as boss, he positioned Merlino as underboss and Ronald Turchi as the consigliere in the new hierarchy.  This administration is still in question to this day, as many now believe that Merlino was running the family behind the scenes, letting Natale have the boss position to deter law enforcement from himself.

Gigante was one of five brothers: Mario, Pasquale, Ralph and he all became mobsters in the Luciano family, forerunner of the Genovese family.  Only one brother, Louis, stayed out of the crime family, instead becoming a priest.  Gigante was the shooter in the failed assassination of longtime Luciano boss Frank Costello in 1957.  After sharing a prison cell with Costello's rival, Vito Genovese, following Vito's conviction for heroin trafficking, Gigante became a caporegime, overseeing his own crew of Genovese soldiers and associates that operated out of Greenwich Village.

The Patriarca family is a Mafia crime family based in New England.  Succeeding his father Raymond L.S. Patriarca as boss after his father's death in 1984, Junior was considered a weak leader.

When Junior's original underboss Ilario "Larry Baione" Maria Antonio Zannino was sentenced to thirty years in prison in 1987, it further weakened Junior's position.  With Zannino in jail, Grasso became underboss. This is a list of minor characters in "The Godfather" series.
