With the colonization of the Americas by Italy there are many differences in the culture of this TL and the culture of OTL.
The Italian language becomes a major language throughout the Americas. In the states of Florida, California, Arizona, Texas, Missouri, and Illinois the Italian language is required to learn between the grades of 1st and 5th. In Porto di la dei Caraibi a version of Italian known as Port Italian is spoken. It borrows many words from Spanish and a couple of English words. There are also new words for boy, girl, city, and small.
In the urban streets of Citta di San Marco, Vespugia in OTL west Venezuela you can see many Italian traditions being played out. Similar to the Tex-Mex American Mexican foods there are plenty of forms of American Italian foods that are common dishes of the Americas.
