The origins of these communities goes back to the 11th century when soldiers and settlers from Northern Italy, settled the central and eastern part of Sicily during the Norman conquest of the island. After the marriage between the Norman king Roger I of Sicily with Adelaide del Vasto, member of Aleramici family, many Lombard colonisers left their homeland, in the Aleramici's possessions in Piedmont and Liguria, to settle on the island of Sicily.
