Giuseppe Diana was an Italian Catholic priest and writer from Casal di Principe who lived from 1958 to 1994. Known affectionately as Father Peppino, he was a prominent critic of the Camorra, a criminal organization. He actively worked to protect his community by establishing a center for African immigrants to prevent their exploitation by gangs. His courageous stance against local organized crime and his refusal to cooperate with criminal elements eventually led to his assassination while he was preparing to celebrate Mass.
Resistance to crime

During the 1980s and 1990s, Diana challenged the influence of the Casalesi clans. He published letters denouncing extortion, illegal drug trafficking, and corrupt construction practices. He even threatened to withhold religious sacraments from members of the criminal organization. By supporting local political efforts to block corrupt business tenders, he sought to dismantle the systemic control held by the Camorra over his region.
Death and legacy
In March 1994, Diana was murdered by the Camorra after testifying in investigations regarding ties between criminals, politicians, and businessmen. His life influenced the writer Roberto Saviano, who dedicated a chapter in the book Gomorrah to him. The book's title itself was inspired by a letter written by the priest. In 2014, Pope Francis honored his memory by wearing a garment previously owned by Diana.
