The 'Ndrangheta (/əndræŋˈɡɛtə/, Italian: [(a)nˈdraŋɡeta], Calabrian: [(ɳ)ˈɖɽaɲɟɪta]) is a mafia-type criminal syndicate originating from the Calabria region of Italy. Emerging in the 19th century, it has developed into one of the world's most powerful and pervasive organized crime entities. Characterized by a decentralized, horizontal structure composed of autonomous operating units known as 'ndrine, the organization's foundational structure is based on family and blood relationships. Beginning in the mid-20th century, coinciding with significant emigration from Calabria, 'Ndrangheta clans expanded their operations across Northern and Central Italy, Europe, Australia, and the Americas. The syndicate is reportedly involved in a wide array of illegal activities, including drug trafficking, arms trafficking, money laundering, racketeering, extortion, and loan sharking.
The 'Ndrangheta has historically had a significant ability to influence local, regional and national politics through systemic corruption, intimidation, and collusion, and continues to infiltrate various sectors of the legal economy both within Italy and internationally. Estimates in 2013 suggested the organization's revenue reached €53 billion. A U.S. diplomatic cable from 2010 purportedly estimated that the 'Ndrangheta's illicit activities, encompassing drug trafficking, extortion, and money laundering, accounted for approximately three percent of Italy's GDP. While its origins are contemporary with the Sicilian Cosa Nostra, formal legal designation of the 'Ndrangheta as a Mafia-type organization under Article 416 bis of the Italian penal code occurred in 2010. The Italian Supreme Court of Cassation had reached a similar conclusion in March of the same year.
