Crema, Lombardy
By the 1859 Treaty of Zurich which ended the Austro-Sardinian War, Austria ceded Lombardy, including Crema, to France, who then immediately ceded it to Sardinia. This formed part of the "Risorgimento", which saw Sardinia become the Kingdom of Italy in 1861. In 1946, the Kingdom became the modern Italian Republic.
Savoy
The territory of Savoy was annexed to France in 1792 under the French First Republic, before being returned to the Kingdom of Sardinia in 1815. Savoy, along with the county of Nice, was finally annexed to France by a plebiscite, under the Second French Empire in 1860, as part of a political agreement (Treaty of Turin) brokered between the French emperor Napoleon III and King Victor Emmanuel II of the Kingdom of Sardinia that began the final steps in the process of unification of Italy. Victor Emmanuel's dynasty, the House of Savoy, retained its Italian lands of Piedmont and Liguria and became the ruling dynasty of Italy.
