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.
Argentina–Italy relations
In 1816, Argentina declared its independence from Spain. At the same time, Italy was made up of separate independent Italian states. In May 1836, the Kingdom of Sardinia recognized and established diplomatic relations with Argentina, the first Italian state to do so. In 1842, Italian General (and future unifier of Italy) Giuseppe Garibaldi, fought for Uruguayan rebels during the Uruguayan Civil War against the Argentine Confederation and Uruguayan Nationalist Party.
