I think that the Stidda (The Star) can be a good example:in the 1970s after the Corleonesi killed Giuseppe Di Cristina the boss of Riesi,more of his men was shelved and decided to create their own organization calling it the Stidda and making new members without the Sicilian Commission approval and choosed Gela because there was few men of honor there in 1970s-1980s.
