The Tattaglia family are known to be involved in prostitution run from the Tattaglia Hotel in Brooklyn. They are the first family to begin working with narcotics sometime in the 1930s. In the 1940s, the Tattaglias begin to gain power after being supported by drug kingpin Virgil Sollozzo, even managing to gain a vital toehold into Little Italy, Manhattan, crippling the Corleone family's empire. They are also behind the attempted assassination of Don Vito Corleone.
Their luck would not last for long, however; Bruno Tattaglia is killed by Corleone enforcers, and Sollozzo is murdered by Don Corleone's son Michael. Don Tattaglia declares a state of mob war against Don Corleone, having been secretly backed up by Emilio Barzini.
After being forced into a stalemate, Tattaglia and his allies set up Sonny Corleone for assassination, avenging Bruno's death. Vito, having recovered, calls a meeting of The Commission. At the meeting, Tattaglia demands assurances from Vito that as time goes on and the Corleones become more powerful, they will not attempt "an individual vendetta" against him for having had Sonny killed. Vito says that after the deaths of their respective sons, he and Tattaglia "are quits," or even, and rhetorically asks whether further acts of vengeance will bring either of their sons back to life. He swears that he will not fight Tattaglia as long as Michael remains safe and the two men ceremonially embrace and exchange kisses, to the applause of the other Mafia chieftans in the room, as Barzini looks on approvingly. However, despite his flowery words and their embrace, Corleone still secretly harbors contempt and animosity towards Tattaglia. On the car ride back from the meeting, Corleone tells his consigliere, Tom Hagen, that "Tattaglia is a pimp. There's no way that he could have out-fought Santino (Sonny)," revealing his sudden realization that Barzini, not Tattaglia, was the mastermind behind the other Families' war against the Corleones.
This peace arrives just in time, as the Tattaglia family have been crippled by the war. However, after Vito Corleone dies of a heart attack, Michael — the new Don of the Corleone family — sends Rocco Lampone to the Saint Sebastian Hotel, where he and another Corleone soldier surprise Don Tattaglia while he is in bed with one of his prostitutes and murder him in a hail of machine-gun fire, as part of Michael's sweeping and ultimately successful plan to kill the heads of all of the other New York Families as well as all of the Corleones' other enemies and traitors within their midst.
The new regime
In 1979, Altobello betrays Michael Corleone to Don Licio Lucchesi and the corrupt members of the Vatican Bank. As retribution, Michael's nephew and successor, Vincent Corleone, orders both Lucchesi and Altobello killed, thus leaving the fate of the Tattaglia Family unknown.
