The Franco-Austrian War of 1859 was the agent that began the physical process of Italian unification. ... The northern Italian states held elections in 1859 and 1860 and voted to join the Kingdom of Piedmont-Sardinia, a major step towards unification, while Piedmont-Sardinia ceded Savoy and Nice to France.
