Hi, this is a pretty common question in this sub; not discouraging additional, more in-depth, or new information here, but meanwhile you can check out a few previous answers:
How did Italians "become white"? - includes a link that leads to several more threads
Can anyone elaborate on divisions within the Italian community on "whiteness"?
I remember a great-grand uncle telling me that "we are nothing like those mafia-tangled Neapolitans or Sicilians--they are a dark, swarthy people. We don't associate them them. We're Northern Italians from so far north we're Swiss!"
So were there Italian immigrants who saw themselves as and/or were perceived as "white" in contrast to Italian immigrants from other areas, and who received any different treatment?
