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.
Sardinian medieval kingdoms
In 807, 810-812, and 821-822 the Arabs of Spain and North Africa tried to invade the island but the Sardinians resisted several attacks. This defence was so effective that in a letter in 851, Pope Leo IV asked the "Iudex Provinciae" (judge of the province) of Sardinia, based in Caralis, for aid in the defense of Rome. With the fall of the Exarchate of Africa, based in Carthage, in the eighth century, and especially with the emergence of the Arab presence in Sicily (827), Sardinia remained disconnected from Byzantium and had, out of necessity, become economically and militarily independent.
