The existing Kingdom of Piedmont-Sardinia, together with the agriculturally rich Po Valley all the way to the Soča River, and along with the entire northern (Romagna) part of the Papal States (the so-called "Papal Legations"), would become The Kingdom of Upper Italy ("Alta Italia"), under the king of Piedmont-Sardinia ("...sotto la guida di Vittorio Emanuele").[1] The southern part of the Papal States, with the exception of Rome and its immediate surrounds, was to be merged with Tuscany in order to create a Kingdom of Central Italy ("Regno dell’Italia centrale"). The Grand Duke of Tuscany, Leopold II, another Austrian ally and great-grandson of Maria Theresa, would need to go.
