Charles "Lucky" Luciano was an Italian-born gangster who operated mainly in the United States. Luciano started his criminal career in the Five Points Gang and was instrumental in the development of the National Crime Syndicate. Luciano is considered the father of modern organized crime in the United States for the establishment of the Commission in 1931, after he abolished the boss of bosses title held by Salvatore Maranzano following the Castellammarese War. He was also the first official boss of the modern Genovese crime family.
Salvatore Maranzano, nicknamed Little Caesar, was an Italian-American mobster from the town of Castellammare del Golfo, Sicily, and an early Cosa Nostra boss who led what later would become the Bonanno crime family in New York City. He instigated the Castellammarese War in 1930 to seize control of the American Mafia, winning the war after the murder of rival faction head Joe Masseria in April 1931. He then briefly became the Mafia's capo di tutti capi and formed the Five Families in New York City, but was murdered on September 10, 1931, on the orders of Charles "Lucky" Luciano, who established The Commission, in which families shared power to prevent future turf wars.
Giuseppe "Joe the Boss" Masseria was an early Italian-American Mafia boss in New York City. He was boss of what is now called the Genovese crime family, one of the New York City Mafia's Five Families, from 1922 to 1931. In 1930, he battled in the Castellammarese War to take over the criminal activities in New York City. The war ended with his murder on April 15, 1931, in a hit ordered by his own lieutenant, Charles "Lucky" Luciano, in an agreement with rival faction head Salvatore Maranzano.
John Donato Torrio was an Italian born-American mobster who helped build the Chicago Outfit in the 1920s later inherited by his protégé Al Capone. Torrio proposed a National Crime Syndicate in the 1930s and later became an adviser to Lucky Luciano and his Luciano crime family.
The Castellammarese War was a bloody power struggle for control of the Italian-American Mafia that took place in New York City, New York, from February 1930 until April 15, 1931, between partisans of Joe "The Boss" Masseria and those of Salvatore Maranzano. The war was named after the Sicilian town of Castellammare del Golfo, the birthplace of Maranzano. Maranzano's faction won and divided New York's crime families into the Five Families; Maranzano declared himself capo di tutti i capi. However, Maranzano was murdered in September 1931 on orders of Lucky Luciano, who established a power-sharing arrangement called the Commission, a group of Mafia families of equal stature, to avoid such wars in the future.
Vincent Drucci, also known as "The Schemer", was an American mobster during Chicago's Prohibition era who was a member of the North Side Gang, Al Capone's best known rivals. A friend of Dean O'Banion, Drucci succeeded him by becoming co-leader. He is the only American organized crime boss to have been killed by a policeman.
Francesco Ioele, known as Frankie Yale or Frankie Uale, was an American gangster based in Brooklyn and the second employer of Al Capone.
William J. "Wild Bill" Lovett was an Irish American gangster in early 20th century New York.
The Genna crime family, was a crime family that operated in Prohibition-era Chicago. From 1921 to 1925, the family was headed by the six Genna brothers, known as the Terrible Gennas. The brothers were Sicilians from the town of Marsala and operated from Chicago's Little Italy and maintained control over the Unione Siciliana. They were allies with fellow Italian gang the Chicago Outfit. After a bloody war led to their demise in the 1920s, the gang was eventually absorbed by the Chicago Outfit.
The Irish Mob is a usually crime family-based ethnic collective of organized crime syndicates composed of primarily ethnic Irish members which operate primarily in Ireland, the United States, the United Kingdom, Canada and Australia, and have been in existence since the early 19th century. Originating in Irish-American street gangs – famously first depicted in Herbert Asbury's 1927 book, The Gangs of New York – the Irish Mob has appeared in most major U.S. and Canadian cities, especially in the Northeast and the urban industrial, including Boston, New York City, Philadelphia, Pittsburgh, Baltimore, Cleveland, and Chicago.
Giuseppe "Joe" Aiello was a Sicilian bootlegger and organized crime leader in Chicago during the Prohibition era. He was best known for his long and bloody feud with Chicago Outfit boss Al Capone.
Jewish-American organized crime initially emerged within the American Jewish community during the late 19th and early 20th centuries. It has been referred to variously in media and popular culture as the Jewish Mob, Jewish Mafia, Kosher Mob, Kosher Mafia, and Kosher Nostra or Undzer Shtik. The last two of these terms are direct references to the Italian cosa nostra; the former is a play on the word for kosher, referring to Jewish dietary laws, while the latter is a calque of the Italian phrase 'cosa nostra' into Yiddish, which was at the time the predominant language of the Jewish diaspora in the United States.
The Atlantic City Conference held between 13–16 May 1929 was a historic summit of leaders of organized crime in the United States. It is considered by most crime historians to be the earliest organized crime summit held in the US. The conference had a major impact on the future direction of the criminal underworld and it held more importance and significance than the Havana Conference of 1946 and the Apalachin meeting of 1957. It also represented the first concrete move toward a National Crime Syndicate.
Richard Joseph "Peg Leg" Lonergan was an American underworld figure and labor racketeer. He was a high-ranking member and the final leader of the White Hand Gang. He succeeded Bill Lovett after his murder in 1923 and, under his leadership, led a two-year campaign against Frankie Yale over the New York waterfront until he and five of his lieutenants were killed in South Brooklyn during a Christmas Day celebration at the Adonis Social Club in 1925.
Charles Dean O'Banion was an American mobster who was the main rival of Johnny Torrio and Al Capone during the brutal Chicago bootlegging wars of the 1920s. The newspapers of his day made him better known as Dion O'Banion, although he never went by that first name. He led the North Side Gang until 1924, when he was shot and killed, reportedly by Frankie Yale, John Scalise and Albert Anselmi.
Black Hand extortion was a criminal tactic used by gangsters based in major cities in the United States. In Chicago, Black Hand extortion began around 1900 and had all but faded away by 1970, replaced by the Mafia. The Mafia was initially organized by Johnny Torrio and further organized by Al Capone into the extant Chicago Outfit sometime later. Black Handers in Chicago were mostly Italian men from Calabria and Sicily who would send anonymous extortion notes to their victims emblazoned with a feared old country symbol: the "Black Hand". The Black Hand was a precursor of organized crime, although it is still a tactic practiced by the Mafia and used in organized crime to this day. The Black Hand gangsters of this time period differed from the Mafia by lacking formally structured hierarchies and codes of conduct, and many were essentially one-man operations. Black Hand blackmail was also common in New York, Boston, and New Orleans. Victims would be threatened with being beaten, shot, or have their place of business bombed if they did not pay. Starting around 1909, Black Hand activity was causing difficulties for mob boss Big Jim Colosimo, a former Black Hand gangster and owner of brothels throughout Chicago. Colosimo's life was being threatened with demands for cash to ensure his physical safety. In an effort to fix the problem, he recruited Johnny Torrio, who was a member of New York's Five Points Gang at the time, to come to Chicago. Torrio would later become the famous successor to Big Jim Colosimo and mentor Al Capone as the organized crime ruler of Chicago.
