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 Sardinia
In 240 BC, in the course of the First Punic War, the Carthaginian mercenaries on the island revolted and gave the Romans, who some years earlier had defeated the Carthaginians in the naval battle of Sulci, the opportunity to land on Sardinia and occupy it. In 238 BC the Romans took over the whole island, without meeting any resistance. They took over an existing developed infrastructure and urbanized culture (at least in the plains). Along with Corsica it formed the province of Corsica et Sardinia, under a praetor. Together with Sicily it formed one of the main granaries of Rome until the Romans conquered Egypt in the 1st century BC.
