The 'Ndrangheta is an Italian Mafia-type association based in the peninsular region of Calabria and dating back to the 19th century. Although loosely structured, it is considered one of the most powerful organized crime groups in the world. It is characterized by a horizontal structure made up of autonomous clans known as 'ndrine, based almost exclusively on blood ties. Since the 1950s, following wide-scale emigration from Calabria, 'Ndrangheta clans dispersed to other European countries, Australia and the Americas. Currently, its main activity is drug trafficking, but it also deals with arms trafficking, money laundering, racketeering, extortion, and loan sharking.
