I believe that Cosa Nostra and Stidda have fought. I believe Provenzano while a fugitive had disputes that resulted in people dying with the Stidda


Cosa Nostra killed a lot of them , even Matteo Messina Denaro killed some of them personally.

About Stidda in Marsala.

All started with the murders of Francesco Caprarotta and Vincenzo D'Amico, boss and underboss of Marsala crime family, disappeared in 1992 killed by the 'Corleonesi' after a meeting attended by Toto Riina, Mariano Agate, Matteo Messina Denaro and Antonio Patti.
After these murders Carlo Zichittella, member of Cosa Nostra crime family based in Marsala, founded a Stidda family in the town supported by Giuseppe Grassonelli and Orazio Paolello, bosses of the Stidda in Porto Empedocle and Gela, in order to fight the 'Corleonesi'.

The Stidda came into public view when Cosa Nostra pentito Francesco Marino Mannoiaspoke about it in 1989. Later another Mafia member Leonardo Messina told his own view. According to their testimonies, Stidda is an organisation that was founded by former members of the Cosa Nostra during the Second Mafia War of the early 1980s. They had been expelled due to disobedience or, in a couple of cases, even marrying a relative of a police officer. Many of the original stiddari were followers of the murdered Mafia-boss Giuseppe Di Cristina.

The Stidda was particularly strong in southern Sicily around the towns of Agrigento, Caltanissetta, Gela, Vittoria, Niscemi and others smaller.
The original leaders of the Stidda were Giuseppe Croce Benvenuto and Salvatore Calafato. A dynamite bomb later killed Stidda boss Calogero Lauria. They were involved a more direct war with the Mafia in the early 1990s. The vicious war led to over 300 deaths.One of these was the judge Rosario Livatino.
