#1 La Cosa Nostra

The Mafia, The Mob, The Family, La Cosa Nostra, it goes by many names, but none are official, as members will swear up and down that this organization doesn't exist. The Italian mob which is mostly active in the United States and Sicily is probably the most infamous organized crime syndicate in the world. Lionized in such classic films as 'The Godfather' trilogy, Goodfellas, Donnie Brasco, and countless more, the mob rose to great heights in America thanks to prohibition. Prohibition laid the groundwork for smuggling and bootlegging which can largely be held responsible for laying the groundwork for organized crime drug smuggling that still exists today. Although many people think of The Mafia as a relic of the past, they are actually still very active today in activities including extortion, murder-for-hire, political corruption, racketeering and arms trafficking.
