I’m Sicilian on my father’s side, and I kinda generally knew a lot of people conquered it over the years, but damn. I did a Google search for “conquered Siciliy” and I’m not sure who didn’t conquer them. I think I got drunk and conquered them once.
Here’s what I got (in no particular order):

Am I missing anyone?
