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.
Sardinia and Corsica
Even though Rome had drawn up an earlier treaty with Carthage following the First Punic War, a complete disregard to this agreement led them to forcibly annex Sardinia and Corsica during the Mercenary War. In 238 BC, the Carthaginians, accepting defeat in the First Punic War, surrendered Corsica and Sardinia, which together became a province of Rome. This marked the beginning of Roman domination in the Western Mediterranean. The Romans ruled this area for 694 years.
