Title explains it all. For research on a revival of one of my TLs. I've done some research on the subject already, but what I'm really lacking is a detailed geographic distribution of areas that would support a large communist/socialist movement in Italy around WWI. I have conflicting sources, some saying it would be centered on Milan (which I'm inclined to believe), but also some that say the poorer Southern regions would be more ripe for the movement. Any help would be appreciated.
