The Morello crime family was one of the earliest crime families to be established in the United States and New York city. The Morello crime family was based in Manhattan's East Harlem and would establish dominance over the New York Sicilian mafia families operating in the Italian-American underworld. The crime family eventually gained dominance in the Italian underworld by defeating the rival Neapolitan Camorra of Brooklyn. Many of the organizations members included such criminals as Ignazio "Lupo the Wolf" Saietta, Giuseppe "Joe the Boss" Masseria, Francesco "Frankie Yale" Uale, Umberto "Rocco" Valenti, Tomasso "The Ox" Petto and Charles Ubriaco as well as others becoming future leaders of the "Five Families" such as Charles "Lucky" Luciano, Frank "the Prime Minister" Costello, Vito Genovese and Giuseppe "Joe Adonis" Doto. The Morello crime family's successors would gain control of New York city's criminal rackets following the fall of the Irish and Jewish gangsters who dominated New York's underworld in the beginning of the twentieth century.
