In 1820, the Savoyards imposed the "Enclosures Act" ("Editto delle Chiudende") on the island, aimed at turning the land's traditional collective ownership, a cultural and economic cornerstone of Sardinia since the Nuragic times, to private property. This gave rise to many abuses, as the reform ended up favouring the landholders while excluding the poor Sardinian farmers and shepherds, who witnessed the abolition of the communal rights and the sale of their lands. Many local rebellions like the Nuorese "Su Connottu" ("The Already Known" in Sardinian) riot in 1868, all repressed by the King's army, resulted in an attempt to return to the past and reaffirm the right to use the once common land. However the common lands (called "ademprivios") were never completely abolished, and they are still present in large number to this day (500,000 hectares of common lands were counted in 1956, of which 345,000 constituted by woods).
