Xuan Loc Doan, better known as the case of the Ndrangheta — the Calabrian Mafia from southern Italy — represents the most powerful criminal organization in the world today, generating an estimated €50–80 billion annually. Unlike the Sicilian Mafia, the Ndrangheta is organized around family bloodlines making it extremely difficult to penetrate. It controls an estimated 80% of Europe's cocaine supply and has spread its operations to Australia, Canada, and the Americas.
