Giuseppe Di Cristina (April 22, 1923 – May 30, 1978) was a powerful mafioso from Riesi in the province of Caltanissetta, Sicily, southern Italy.

[1] Don Ciccu was a clever boss and developed good relationships with the Palermo Mafia families and political groups.

[1] Di Cristina was known as the ‘elector’ of Calogero Volpe, an MP for Christian Democrat party (DC – Democrazia Cristiana).

[1] Giuseppe's brother Antonio Di Cristina would become the mayor of Riesi and the under-secretary of the Christian Democrat party of the Caltanissetta province.

[1] After he returned from an internal banishment in Turin due to the Mafia crackdown by the Italian authorities after the Ciaculli massacre in 1963, Di Cristina was made treasurer of the EAS-owned company So.

[3] Di Cristina changed sides in his political preferences because he got no support from the Christian Democrats when he was in trouble over a restraining order.

Despite the upheaval about Gunnella's relationship with Di Cristina, he was defended by Republican Party leader Ugo La Malfa.

[3] According to the pentito Tommaso Buscetta, Di Cristina was involved in the killing of Enrico Mattei, the controversial president of the state oil company Ente Nazionale Idrocarburi (ENI) who died in a mysterious plane crash on October 27, 1962.

One of the first issue that had to be confronted was an offer of prince Junio Valerio Borghese who asked for support for his plans for a neofascist coup in return for a pardon of convicted mobsters like Vincenzo Rimi and Luciano Leggio.

In yet another trial in Agrigento over a vendetta between Mafia clans in Riesi and Ravanusa over a refusal to stash a load of smuggled cigarettes belonging to Di Cristina.

Russo, who according to the Corleonesi was a confidant of Di Cristina, was killed without the consent of the Commission, which had opposed a prior request by Totò Riina and Bernardo Provenzano.

The Corleonesi were attacking the allies of the Palermo families in the other provinces to isolate men like Stefano Bontade, Salvatore Inzerillo and Gaetano Badalamenti.

Di Cristina and Badalamenti wanted to kill Francesco Madonia, the boss of Vallelunga Mafia family and an ally of the Corleonesi in the province of Caltanissetta.

Di Cristina gave a full picture of the internal division within Cosa Nostra between the Corleonesi led by Luciano Leggio and the faction of Gaetano Badalamenti and Stefano Bontade.

The Corleonesi had a secret death squad of fourteen men and were infiltrating other mafia families, according to Di Cristina.
