I was reading articles about the Sicilian Mafia

And I came across a statement that suprised me. It seem that criminal groups from Naples, were the one who created the Mafia ? Am I wrong or ?

The Sicilian Mafia was founded in Sicily by elements of the Camorra, a crime organization established in Naples, in the early 1800's.

The Mafia began as an extralegal force in the 19th century, during the reign of the Bourbons of Naples, and coinciding with Sicily's transition from feudalism to capitalism. Under feudalism, the nobility owned most of the land and enforced the law through their private armies and manorial courts. After 1812, the feudal barons steadily sold off or rented their lands to private citizens.
