Joseph Lonardo, also known as "Big Joe", was a Sicilian emigrant to the United States who became the first crime boss of the Cleveland crime family, which he structured from a number of competing organized crime gangs. When national Prohibition began in 1920, Lonardo became a dealer in corn sugar, an essential ingredient in the manufacture of corn whiskey. Lonardo became a "sugar baron" by driving other legitimate corn sugar merchants out of business, encouraging home distillation, and using intimidation, murder, and theft to eliminate or drive his criminal competitors out of business.

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, as 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 family. Under the control of the family's longest-serving boss, John T. Scalish, who led the organization from 1945 until 1976, the Cleveland Mafia exerted influence over the Teamsters union, profiting from labor racketeering and the skimming of revenue from Las Vegas casinos.
