In some ways, organized crime groups in America operate like businesses. The most enduring syndicates have adapted to America’s changing landscape, much like corporations. Some criminal enterprises that emerged in the late 1800s still maintain influence today.
24/7 Tempo has compiled a list of the biggest gang dynasties in America. We created our list using sources such as the Crime Museum, American Mafia History, Mafia History, government sources such as FBI.gov, as well as online encyclopedias like Britannica, and media sources including American Magazine.
According to sources like the FBI, many major crime groups originated in Atlantic coast cities among late 19th century immigrant populations. These newcomers provided targets for extortion, gambling, and other rackets. As unionization grew, mobsters infiltrated labor. Over decades, trash collection, trucking, narcotics, and gambling offered lucrative avenues for organized crime.
After World War II, narcotics became a major income source. Later, when Las Vegas and Atlantic City legalized casinos, mobsters carved out a substantial piece of the profits. Just like multigenerational corporations, mob dynasties have shown staying power by diversifying and seizing new opportunities. Though their methods are illegal, major crime syndicates demonstrate the durability of any enterprise that provides desired services.
When Las Vegas became the gambling mecca of the nation after the war, and after Atlantic City legalized casino gambling in 1977, organized crime got more than just a piece of the action. (These are the most infamous white collar scandals in history.)
