The Mazzarino Friars were a group of Capuchin friars that turned to crime. They were active around the town of Mazzarino, Italy, in the 1950s. Their trial was a much-debated issue in the early '60s in Italy, in the context of the historical struggle between clerical and anti-clerical political forces prominent at that time.
The whole story was pieced together in 1989 by journalist Giorgio Frasca Polara in his book La Terribile Istoria dei Frati di Mazzarino (The Terrible History of the Mazzarino Friars), published by Sellerio.
