Tom Hagen is an unofficial member of the Corleone family inThe Godfather, but the movie leaves it unclear how and when the family adopted him. Tom is one ofthe most iconic characters inThe Godfathertrilogy, and one of the Corleones’ most trusted allies. Although he’s not a Corleone in name, he’s as much a son to Don Vito Corleone as Michael, Sonny, or Fredo. As the family’s lawyer and consigliere, Tom is much more valuable to the Corleone clan than Fredo.

Robert Duvall played the role of Tom inthe cast ofThe GodfatherandThe Godfather Part II, but the character didn’t appear inThe Godfather Part III. The first two movies left Tom’s backstory a mystery, so when he was absent from the threequel, it remained unexplained. In the movies,it’s mentioned that Sonny brought Tom home and ingratiated him into the family, but the novel goes into more detailabout Tom’s biological family and the adoption situation.

After attending law school and getting his degree, Tom became Vito’s personal lawyerhandling the Corleone family’s affairs. By tradition,Tom’s non-Italian heritage prohibited him from taking on a formal position within the mafia family, but Vito nonetheless made him the new consigliere after Genco Abbandando died. This caused the other New York crime families to mockingly describe the Corleones as “The Irish Gang.”

Vito Was Similarly Taken In By A Friend’s Family

Tom’s backstory is almost identical to Vito’s own childhood.Much like Tom, Vito was taken in by a friend’s family at a young ageand raised as one of their own. Vito was similarly orphaned and living on the streets of New York whena childhood friend, Genco, convinced his parents to take him in. When Sonny brought Tom home and asked for him to be given a home and raised with love before the events ofThe Godfather, Vito undoubtedly saw himself in the young lad.
