Bernardo Provenzano was a member of the Mafia (Cosa Nostra) and is suspected of having been the head of the Corleonesi, a Mafia faction that originated in the village of Corleone, and de facto capo di tutti capi (boss of bosses) of the entire Sicilian Mafia until his arrest in 2006.
His nickname is Binnu u tratturi (Sicilian for "Binnie the tractor") because, in the words of one informant, "he mows people down." Another nickname is The Accountant due to his apparently subtle and low-key approach to running his crime empire, at least in contrast to some of his more violent predecessors.
On 13 July 2016, Provenzano died in Milan from complications from bladder cancer, aged 83. Provenzano was refused a public funeral by the church and Palermo police chief. Provenzano was cremated in Milan, and on 18 July, his ashes were buried in his family tomb in a cemetery in his hometown of Corleone.
