I think Sardinia bandits never get this kind of protection. Never forgett after the II WW cosa nostra was finish. But they get "green light" to rebuild because they need them to fight against left groups.
Sardinia never had a secret society like CN. But of course they have criminals groups. In old days they also had vendettas.
Good point.
The Corsican mob also benefited greatly from the end of WW2. They played a key role in the French Resistance networks and were rewarded when the war was over. They were given control of the gambling clubs in Paris (called "Cercles de jeux") which are, to this day, the only gambling places allowed in the Paris area. The Corsicans were already running Marseille underworld, turning it into the drug capital of the world for some time, and the decision to have them run the Paris gambling clubs allow them to get a piece of the Paris underworld, making them the biggest CO in France. Finally, Corsicans are also heavily involved in gambling in French speaking Africa and that also goes back to the post WW2 era.
So I guess, as you said, one of the reasons why Sardinians didn't follow the path of their Sicilian and Corsican cousins is also because they were not given the same opportunities at the end of WW2.
