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.
History of Cagliari
After the failed attempt at conquest of Sardinia by the Spanish Muslim Mujāhid al-ʿĀmirī in about 1016, the kingdom was divided into four "giudicati", one of which was named Callaris, in reference to its capital, now modern Cagliari. The Judicatus of Cagliari comprised a large area of the Campidano plain, the mineral resources of the Sulcis region, and the mountain region of Ogliastra. There were three other independent and autonomous "giudicati" in Sardinia: the Logudoro (or Torres) in the northwest, the Gallura in the northeast, and in the east the most famous, the long-lived Giudicato of Arborea, with Oristano as its capital.
