As a nation state, Italy has emerged only in 1871. Until then the country was politically divided into a large number of independant cities, provinces and islands. The currently available evidences point out to a dominant Etruscan, Greek and Roman cultural influence on today's Italians.
Spain recently advertised that persons with Sephardic jewish names who had ties to Spain could regain their Spanish citizenship and thereby UE citizenship as well. Since so many jews in Spain fled to the Spanish colonies (Italy was a spanish colony from 1559-1713) many fled to Sicily and Southern Italy as well as northern Europe and western hemisphere colonies in Central and south America. So If you have a jdewish Sephardic name you might obtain a European union passport and citizenship in one fell swoop!!!!!!!
