Mobster in the context of "Tony Accardo"

Organized crime refers to transnational, national, or local groups of centralized enterprises that engage in illegal activities, most commonly for profit. While organized crime is generally considered a form of illegal business, some criminal organizations, such as terrorist groups, rebel groups, and separatists, are politically motivated. Many criminal organizations rely on fear or terror to achieve their goals and maintain control within their ranks. These groups may adopt tactics similar to those used by authoritarian regimes to maintain power. Some forms of organized crime exist simply to meet demand for illegal goods or to facilitate trade in products and services banned by the state, such as illegal drugs or firearms. In other cases, criminal organizations force people to do business with them, as when gangs extort protection money from shopkeepers. Street gangs may be classified as organized crime groups under broader definitions, or may develop sufficient discipline to be considered organized crime under stricter definitions.

A criminal organization can also be referred to as an outfit, a gangster/gang, thug, crime family, mafia, mobster/mob, (crime) ring, or syndicate; the network, subculture, and community of criminals involved in organized crime may be referred to as the underworld or gangland. Sociologists sometimes specifically distinguish a "mafia" as a type of organized crime group that specializes in the supply of extra-legal protection and quasi-law enforcement. Academic studies of the original "Mafia", the Sicilian Mafia, as well as its American counterpart, generated an economic study of organized crime groups and exerted great influence on studies of the Russian mafia, the Indonesian preman, the Chinese triads, the Hong Kong triads, the Indian thuggee, and the Japanese yakuza.

Thomas Edmund Dewey (March 24, 1902 – March 16, 1971) was an American lawyer and politician who served as the 47th governor of New York from 1943 to 1954. He was the Republican Party's nominee for president of the United States in 1944 and 1948, losing the former election to Franklin D. Roosevelt and the latter election to Harry S. Truman in a major upset.

As a New York City prosecutor and District Attorney in the 1930s and early 1940s, Dewey was relentless in his effort to curb the power of the American Mafia and of organized crime in general. Most famously, he successfully prosecuted Mafia boss Charles "Lucky" Luciano on charges of forced prostitution in 1936. Luciano was given a 30- to 50-year prison sentence. He also prosecuted and convicted Waxey Gordon, another prominent New York City gangster and bootlegger, on charges of tax evasion. Dewey almost succeeded in apprehending mobster Dutch Schultz as well, but Schultz was murdered in 1935, in a hit ordered by the Commission.

John Donato Torrio (born Donato Torrio, Italian: [doˈnaːto ˈtɔrrjo]; January 20, 1882 – April 16, 1957) was an Italian-born 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.

Torrio had several nicknames, primarily "The Fox" for his cunning and finesse. The US Treasury official Elmer Irey considered him "the biggest gangster in America" and wrote, "He was the smartest and, I dare say, the best of all the hoodlums. 'Best' referring to talent, not morals." Virgil W. Peterson of the Chicago Crime Commission stated that his "talents as an organizational genius were widely respected by the major gang bosses in the New York City area". Crime journalist Herbert Asbury affirmed: "As an organizer and administrator of underworld affairs, Johnny Torrio is unsurpassed in the annals of American crime; he was probably the nearest thing to a real mastermind that this country has yet produced".

Paul De Lucia (born Felice De Lucia, Italian: [feˈliːtʃe de luˈtʃiːa]; November 14, 1897 – October 11, 1972), known as Paul Ricca (/ˈriːkə/, Italian: [ˈrikka]), was an Italian-American mobster who served as the nominal or de facto leader of the Chicago Outfit for 40 years. In 1958 he was named "the country's most important criminal" by a Senate crime investigating subcommittee. Ricca died on October 11, 1972.

Joseph John Aiuppa (December 1, 1907 – February 22, 1997), also known as "Joey O'Brien" and "Joey Doves", was an American mobster who became a leader of the Chicago Outfit from 1971 until his skimming conviction in 1986.
