We’re talking centuries old mafia bloodlines. They are throughout Europe & the U.S. not just Italy. Book McMafia studies some of them. Of course Robert Maxwell mentioned in it early on.
“At one time derided by the Sicilian Cosa Nostra and Campanian Camorra mafias, the ’Ndrangheta is by far the most powerful criminal group in Italy and one of the richest in the world. A study by the Demoskopita Research Institute in 2013 estimated it was more financially powerful than Deutsche Bank and McDonald’s combined, with an annual turnover of €53bn (£44bn).
In the course of the investigation, police discovered a pizzino, a small slip of paper used by the mafia for top-level communications, containing a quote from three 17th-century knights who, according to legend, founded the Cosa Nostra in Sicily, the Camorra in Campania and the ’Ndrangheta in Calabria.”
