How did all four Mafia groups start and why Italy?

The more I come to think about it, I have always seen Italy as the most beautiful and cultured country in the world and in many ways that opinion hasn't changed. However the more I grow up and read into various things I can now clearly see it has one of the darkest and sinister sides to it that other European countries in this modern age do not have. Why did these secret societies start? Why are normal Italians today so anti-state, I've always been lead to believe that all throughout the History of the peninsula since Roman times the state has always enriched itself and mistreated the people, causing them to be more individualistic and hostile to authority. Is that partially why many of these societies exist in Italy. It seems to me that Italians are very distrustful of each other and anyone in a position of authority and that is also why they are very family based. Does anyone know anything more on this matter?

According to John Dickie, there is a myth of three Spanish brothers and knights Osso, Mastrosso and Carcagnosso who in the middle ages fled from Spain and took refuge on an island off shore Italy. They had fled because their sister had been raped and killed and they revenged the crime by murdering the perpetrators. On this Italian island they invented the rules of the honored sociaty. Osso then went to Sicily and formed the Sicilian Mafia, Mastrosso went to Naples and formed the Camorra and Carcagnosso went to Calabria and formed the ndrangheta.

This a myth told to all new ndrangheta recruits, I should add.

I talk about Sicily now.State never cared about Sicily,generally south italy,they didn't care much about life of people,they solved all problems by their own,no police,no state.Family and honour was everything.Omerta was created long ago when Spanish conquered Sicily.You still have Vendettas in South Italy.People would turn to local mafia bosses(most powerful man in village)for help,for job,for doctor etc. Not the state,not the police.

Vito Cascioferro once said: "Don't throw people into bankruptcy with ridiculous demands for money. Offer them protection instead, help them to make their business prosperous, and not only will they be happy to pay but they'll kiss your hands out of gratitude."

And btw,you have some Yakuza groups in Japan dating even before Cosa Nostra.
