In the early 1820's most of Italy was still ruled by the same men who had squared off against Napoleon - Grand Duke Ferdinand in Tuscany, King Ferdinand in Naples, and Pope Pius VII in the Papal States. King Victor Emmanuel I had abdicated in 1821 and his brother Charles Felix was now king, but they were men cut from the same cloth, so Piedmont still had a decidedly pre-Napoleonic mindset. There will be a changing of the guard, and by 1831 all of these men will be dead and gone, replaced with new rulers who will be some of the key players in the Italian Unification. We're also going to see another wave of revolutions in that break out in 1831, and which will meet much the same fate as those in 1820 and 21.
