Duchy of Modena and Reggio
Austria ceded Lombardy to France, which, in turn, gave it to Sardinia. Exploiting the collapse of Austrian power in Italy, Sardinia annexed the United Provinces of Central Italy, consisting of the Grand Duchy of Tuscany, the Duchy of Parma, the Duchy of Modena and Reggio and the Papal Legations, on 22 March 1860. Two days later, Sardinia ceded Savoy and Nice to France at the Treaty of Turin as compensation for its assistance.
