Boss (crime) in the context of "Prohibition era"

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.

The Philadelphia crime family, also known as the Bruno–Scarfo crime family, the Philadelphia–Atlantic City crime family, the Philadelphia Mafia, the Philly Mafia, or the Philadelphia–South Jersey Mafia, is an Italian American Mafia crime family based in Philadelphia, Pennsylvania. Formed and based in South Philadelphia, the criminal organization operates throughout the Greater Philadelphia metropolitan area, including South Jersey. The family is notorious for its violence, its succession of violent bosses, and multiple mob wars.

Operating as the Bruno crime family under the 21-year reign of boss Angelo Bruno (1959–1980), the family enjoyed an era of peace and prosperity. A complex dispute involving disgruntled subordinates and territory claims by New York's Genovese crime family led to Bruno's murder in 1980. The killing marked the beginning of years of internal violence for control of the Philadelphia family, leading to a gradual decline in the family's stability.

The Cleveland crime family, also known as the Scalish crime family or the Cleveland Mafia, is an Italian American Mafia crime family based in Cleveland, Ohio, and throughout the Greater Cleveland area. The organization formed during the 1900s, and early leadership turned over frequently due to a series of power grabs and assassinations. In 1930, Frank Milano became boss and was able to bring some stability to the Cleveland family. Under the control of the family's longest-serving boss, John T. Scalish, who led the organization from 1945 until his death in 1976, the Cleveland family exerted influence over the International Brotherhood of Teamsters (IBT), profiting from labor racketeering and the skimming of revenue from Las Vegas casinos. The family's membership peaked at around sixty "made men" during the 1950s.

When Scalish died unexpectedly during heart surgery without naming a successor in 1976, the Cleveland family fell into turmoil. A violent gang war erupted during the late 1970s when Irish mobster Danny Greene attempted to take over the city's criminal rackets. James T. Licavoli, who became boss of the Cleveland family after Scalish's death, hired hitman Ray Ferritto to kill Greene. After several failed attempts on Greene's life, Ferritto succeeded with a car bomb, ending the mob war. The war drew significant law enforcement attention, however, reducing membership and influence of the family. Much of the family's weakening can be attributed to Jimmy Fratianno, who turned government witness and provided the Federal Bureau of Investigation (FBI) with incriminating information on the organization.

A drug lord, drug baron, kingpin, or lord of drugs is a type of crime boss in charge of a drug trafficking network, organization, or enterprise. When a group of independent drug lords collude with each other, in order to improve their profits and dominate the illegal drug trade, they form an organization called a drug cartel.
