The first major pentito (a captured mafioso who collaborated with the judicial system) was Tommaso Buscetta who had lost several allies in the war and began to talk to prosecutor Giovanni Falcone around 1983. This led to the Maxi Trial (1986-1987) which resulted in several hundred convictions of leading mafiosi. When the Italian Supreme Court confirmed the convictions in January 1992, Riina took revenge. The politician Salvatore Lima was killed in March 1992; he had long been suspected of being the main government connection of the Mafia (later confirmed by testimony of Buscetta), and the Mafia was clearly displeased with his services. Falcone and fellow anti-Mafia prosecutor Paolo Borsellino were killed a few months later. This led to a public outcry and a massive government crackdown, resulting in Riina's arrest in January 1993. More and more pentitos started to emerge. Many would pay a high price for their co-operation usually through the murder of relatives. For example, Cosa Nostra defector Francesco Marino Mannoia's mother, aunt and sister were murdered. 
The Corleonesi retaliated with a campaign of terrorism, a series of bombings against several tourist spots on the Italian mainland: the Via dei Georgofili in Florence, Via Palestro in Milan, and the Piazza San Giovanni in Laterano and Via San Teodoro in Rome, which left 10 people dead and 93 injured and caused severe damage to cultural heritage such as the Uffizi Gallery. Bernardo Provenzano took over as boss of the Corleonesi and halted this campaign and replaced it with a campaign of quietness known as pax mafiosi. This campaign has allowed the Mafia to slowly regain the power it once had. He was arrested in 2006, after 43 years on the run.

The main split in the Sicilian Mafia at present is between those bosses who have been convicted and are now imprisoned, chiefly Riina and capo di tutti capi Bernardo Provenzano, and those who are on the run, or who have not been...
