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.
Sulcis
In the Middle Ages the Sulcis was part of a Curatoria of the giudicato of Cagliari which included the entire south-western part of Sardinia. From 1258 to 1355, after the fall of the giudicato, it was under the rule of the pisan della Gherardesca family and then, from 1355, it was incorporated in the Kingdom of Sardinia by the Aragonese.
