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.
Just a comment. When the inquisiiton imposed mass deportation of both the Jews and Arabs in 1492 there was large migrations of Jews to Italy and northern europe while most arabs went back with their caliphs to North Africa if they did not convert to Christiantiy so I imagine by the 1600's their routes were well established.
Many Jews found their way into Sicily (some estimates say 40% of population were jews in Sicily but that is heresay) and southern Italy with the arabs who were swept up in Alexandria by the Caliphs and their troops and when the Moors (arabs) were expelled from Spain and Southern Italy as well since it was under Spanish rule, many of the Jews fled from the south of Italy to the north where their fellow jews migrated from Spain.=Peter=
I am a little confused! Are we considering Voluntary Immigration, Religious Persecution, Jewish diaspora, Isabel and Ferdinand religious decisions regarding Spanish nationals, or the movements of the "Spanish troops"of Carlo V?
Voluntary immigration for whatever reason? This is a very complex issue, lets clarify it.
Should we include the "arabs"? Are we including "arabs" - first, second and following generations born in Spain as part of "Spanish immigration" part of Jewish diaspora?
At this point I have no idea what "mimifo" needs ...
I would like to offer some help, but first learn what it is requested.
