Let’s say after unification Italy is more successful at expanding. Going into the 1900s it is a respectable power. It is able to come out of the world wars better off. They country can be unified whatever way you think is best as long as it is around the same period as otl. You can also start with a later pod if you want involving the world wars. The few rules are Italy has to be a superpower or at least powerful to push back against USSR and US influence by the post world war 2 era at latest. Italy must at least have Libya, Eritrea, Ethiopia, and Somalia. Also, the diaspora population has to be as big as it was as otl or if you want to make it interesting more. What impact would this have on the Italian population abroad especially in countries like the US and Argentina?
