So I was looking at a nice AH map the other day about an "Italian overseas territory" called Nuova Toscana in the area of the Guyanas and the Orinoco river, based on the Thornton Expedition, and I was thinking:
If this somehow happened, how would it have affected the demographics of Argentina, ignoring butterflies and assuming everything else in the colonization process happens the same? I ask about Argentina specifically because more than half of its current population (62.5%) has at least one Italian ancestor, and there are 25 million Italian Argentines.
So, if the Italians actually were successful in establishing such a colony, how would that affect Argentina's demographics? What ethnicity would take the Italians place? How would that affect other things, such as language, culture - specifically football, food?
