The commonly told story of the early American Mafia is often more myth than history. For decades, the accepted narrative held that before 1931, the organization was a collection of feuding gangs, torn apart by a generational war between old-school Sicilian traditionalists and a new wave of Americanized mobsters. This version of events, popularized in films and books, suggests that Charles “Lucky” Luciano single-handedly modernized the Mafia by eliminating the old guard and creating a new, democratic system.
However, modern researchers have found that this story is largely inaccurate. The reality is far more complex, with a gradual evolution rather than a sudden revolution. The old and new schools were not as different as they are often portrayed, and the Mafia’s structure was already developing a system of governance long before Luciano’s rise.
The first credible mentions of the American Mafia date back to the 1870s and 1880s in New Orleans with the Matranga family. Yet, the events that shaped the national organization took place in New York City, which housed the largest Italian diaspora and the five families that would come to define Cosa Nostra.
The history of the New York Mafia is rooted in the story of Giuseppe Morello, considered the first confirmed boss of bosses. Born in Corleone, Sicily, in 1867, Morello fled to the United States in 1893 to escape a prison sentence for counterfeiting. He spent his first years in America working low-paying jobs in Louisiana and Texas, waiting out the three-year period that would make him immune to deportation.

Upon returning to New York in 1897, Morello established himself as a boss and returned to his old trade of counterfeiting. He created a sophisticated operation, using Irish gangsters for distribution to shield his own men from risk. His gang earned significant money, but their activities were confined to the Italian neighborhoods of Little Italy, where they also engaged in protection racketeering and controlled local markets like ice and artichokes.
Morello’s power grew, and by 1903 he had earned the title of Capo di Capi, or boss of all bosses. This title, however, did not make him an all-powerful ruler. Instead, it functioned more like a judge, settling disputes between Mafiosi. This system was overseen by a General Assembly and a Council, which were early forms of the democratic decision-making that would later be formalized.
Morello’s reign ended in 1909 when he was arrested for counterfeiting and sentenced to 25 years in prison. His decapitation plunged the New York Mafia into a period of intense conflict. The families that had been in the shadows emerged to fight for power, leading to a series of bloody wars.
During this time, the five families began to take shape, formed along regional lines from Sicily. The Palermitani, Corleonesi, and Castellammare clans each had their own bosses and territories. These groups were bound by kinship and shared origins, with new arrivals being vetted by leaders who knew their families back in Sicily.

The first Mafia War was a conflict between the powerful Palermitani boss, Salvatore “Toto” D’Aquila, and a coalition of other families. D’Aquila emerged victorious, but his dominance was soon challenged by a new threat: the Brooklyn Camorra, a rival Italian criminal organization from Naples. The Camorra saw an opportunity to seize territory from the weakened Morello family, leading to a brutal conflict that ended only when a former Camorra member turned informant and sent their leadership to prison.
When Giuseppe Morello was released from prison in 1920, he returned to a fractured organization. He quickly clashed with D’Aquila, leading to a second Mafia War. Morello was eventually sentenced to death by a General Assembly, but a powerful ally, Nicolo Gentile, spent years traveling the country to have the sentence overturned. The conflict continued, and Morello, unable to lead his family himself, supported Joe Masseria as the new boss.
Masseria, known as Joe the Boss, was a different kind of leader. He was the first to openly accept non-Sicilians into the Mafia, including mainland Italians like Frank Costello and Vito Genovese. This innovation, along with the immense profits of Prohibition-era bootlegging, changed the nature of the organization. The Mafia was not forced to cooperate with non-Italians by Prohibition, but it created new opportunities and alliances.
Masseria’s aggressive expansion and attempts to control other cities eventually led to the Castellammarese War. Salvatore Maranzano, a high-ranking Sicilian, rallied a coalition of families against Masseria. The war was marked by assassinations and shifting alliances. Masseria lost key allies, including his strategist Giuseppe Morello, who was murdered in 1930.

Facing defeat, Masseria’s own men, led by Charles Luciano, conspired with Maranzano. In April 1931, Masseria was killed in a restaurant, ending the war. Maranzano declared himself the new boss of all bosses, but his reign was short-lived. He immediately began planning to eliminate his former allies, including Luciano. In September 1931, Maranzano was murdered in his office by Luciano’s men.
The creation of the Commission after Maranzano’s death is often credited to Luciano as a revolutionary reform. In reality, it was an evolution of the existing system. The General Assembly and Council had already provided a form of collegial decision-making. The Commission simply formalized this process, creating a body of the strongest family bosses to settle disputes and reduce the subjectivity of a single leader.
The Castellammarese War was not a battle between a progressive new school and a traditionalist old school. The participants themselves did not view it that way. Masseria, often cast as the traditionalist, was the first to accept non-Sicilians. The conflict was a power struggle, driven by the ambitions of individual bosses and the desire to control the lucrative illegal markets of the era.
The early history of the Mafia is not a story of a single man changing everything. It is a story of gradual evolution, marked by mistakes, violence, and the constant search for a stable system of governance. The Mafia that emerged from these wars was not a new creation, but the product of decades of conflict and adaptation.
