The Second Mafia War was a period of conflict involving the Sicilian Mafia, mostly taking place from 1981 to 1984 and involved thousands of homicides. Sometimes referred to as The Great Mafia War or the Mattanza (Italian for 'Slaughter'), it involved the entire Mafia and radically altered the power balance within the organization. In addition to the violence within the Mafia itself, there was violence against the state, including a campaign of deliberate assassinations of judges, prosecutors, detectives, politicians, activists and other ideological enemies. In turn, the war resulted in a major crackdown against the Mafia, helped by the pentiti, Mafiosi who collaborated with the authorities after losing so many friends and relatives to the fighting. In effect, the conflict helped end the secrecy of the Mafia.

Preceding events

The instigators of the Second Mafia War were the Corleonesi, the Mafia Family from the town of Corleone, although they were helped by a number of other Mafia Families. Hailing from a small rural town, the Corleonesi were often referred to as "the peasants" – i viddani in Sicilian – by other Mafia Families, especially by the powerful urbanized bosses in the capital of Palermo. Things began to change in the 1960s as the Corleonesi grew in power and prestige under the leadership of the brutal and ambitious Luciano Liggio, who had become the Mafia boss of Corleone via the crude but effective method of simply shooting the old one, Michele Navarra.

Second Mafia War

During the 1970s the Mafia in Sicily resumed its normal illicit business after the Mafia Trials of the 1960s had ended with few convictions. The Corleonesi's primary rivals were Stefano Bontade, Salvatore Inzerillo and Gaetano Badalamenti, bosses of various powerful Palermo Mafia Families. The Sicilian Mafia Commission was re-established in 1970, with Bontade and Badalementi making up two of the three leaders of the Commission. The third was Liggio, although he was represented by Salvatore Riina as Liggio was in hiding on the Italian mainland. When Liggio was captured in 1974 and imprisoned for murder, Riina soon took over as boss of the Corleonesi with Bernardo Provenzano.

Second Mafia War

The Corleonesi began to win over allies amongst other Mafia Families. Amongst those who aligned themselves with the Corleonesi were Palermo bosses Giuseppe Calò (boss of Porta Nuova), Filippo Marchese (boss of Corso Dei Mille) and Rosario Riccobono (boss of Partanna Mondello). In 1978, Riina managed to have Badalamenti expelled from the Commission, accused of having organised the assassination of Francesco Madonia (boss of Vallelunga and ally of the Corleonesi) and subsequently exiled from the Mafia and Sicily altogether. His place was taken by Ciaculli Godfather Michele "The Pope" Greco, who was also aligned with Riina. Greco, like Calò, Marchese and Riccobono, kept his alliance secret from the likes of Bontade and Inzerillo.

Second Mafia War

It was also in 1978 that Riina arranged for the murders of Giuseppe Di Cristina and Giuseppe Calderone, bosses of Riesi and Catania respectively. Both men were allies of Bontade and Inzerillo; their successors were allies of Riina, who sponsored them. Gradually, the bosses of Palermo and their men were isolated.

The Great Mafia War

On 23 April 1981, Bontade was machine-gunned to death, and a few weeks later, on 11 May, Inzerillo was killed in a hail of bullets. Various relatives and associates of the pair were subsequently killed or vanished without trace, including Inzerillo's 15-year-old son, who was killed for vowing to avenge his murdered father. On 29 September of the same year, Calogero Pizzuto, another close ally of Bontade and Inzerillo, was shot dead in a crowded bar alongside two innocent bystanders. Badalamenti only managed to survive by fleeing Sicily after the Corleonesi had him expelled in the late 1970s.
