The Mafia became an essential part of the social structure in the late 19th century because of the inability of the Italian state to impose its concept of law and its monopoly on violence in a peripheral region. The decline of feudal structures allowed a new middle class of violent peasant entrepreneurs to emerge who profited from the sale of baronial, Church, and common land and established a system of clientage over the peasantry. The government was forced to compromise with these "bourgeois mafiosi," who used violence to impose their law, manipulated the traditional feudal language, and acted as mediators between society and the state.
