What territories did Piedmont gain after the peace settlement of 1859?

Following the peace settlement of 1859, which concluded the Second Italian War of Independence, Piedmont gained most of Lombardy.12

While the initial plans for the war had envisioned a larger territorial expansion, the armistice at Villafranca and the subsequent Treaty of Zurich resulted in a more limited outcome. Specifically, Piedmont did not acquire Venetia or the central Italian duchies at that time, and the settlement excluded the fortress cities of Mantua and Peschiera from the transfer of Lombardy.12

It is important to note that while the 1859 settlement itself provided only these gains, the political momentum initiated by the war led to further annexations in early 1860, when Piedmont incorporated Tuscany and other central regions following plebiscites.13
