John Joseph Gotti Jr. was an American mafioso and boss of the Gambino crime family in New York City. He ordered and helped to orchestrate the murder of Gambino boss Paul Castellano in December 1985 and took over the family shortly thereafter, leading what was described as the most powerful crime syndicate in the United States.
Gotti and his brothers grew up in poverty and turned to a life of crime at an early age. Gotti quickly became one of the Gambino family's biggest earners and a protégé of Aniello Dellacroce, the family's underboss, operating out of Ozone Park, Queens. Following the FBI's indictment of members of Gotti's crew for selling narcotics, Gotti began to fear that Castellano would kill him and his brother Gene for dealing drugs. As this fear continued to grow, and amidst growing dissent over the leadership of the family, Gotti arranged the mutiny murder of Castellano.
At his peak, Gotti was one of the most powerful and dangerous crime bosses in the United States. While his peers generally avoided attracting attention, especially from the media, Gotti became known as "the Dapper Don" for his expensive clothes and outspoken personality in front of news cameras.
