 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.The Normans began a process of "latinization" of Sicily by encouraging an immigration policy of their people, French (Norman, Provencal and Breton) and northern Italians (in particular from Piedmont and Liguria) with the granting of lands and privileges.The aim of the new Norman kings was to strengthen the "Latin stock" which in Sicily was a minority compared to the more numerous Greek and Arab populations.
