Count (1810-1861) Italian nationalist politician, a leading figure in the Italian Risorgimento. As prime minister of Piedmont 1852–59 and 1860–61, he enlisted the support of Britain and France for the concept of a united Italy, achieved 1861; after expelling the Austrians 1859, he assisted Garibaldi in liberating southern Italy 1860.
Cavour was born in Turin, served in the army in early life and entered politics in 1847. From 1848 he sat in the Piedmontese parliament and held cabinet posts 1850–52. As prime minister, he sought to secure French and British sympathy for the cause of Italian unity by sending Piedmontese troops to fight in the Crimean War. In 1858 he had a secret meeting with Napoleon III at Plombičres, where they planned the war of 1859 against Austria, which resulted in the union of Lombardy with Piedmont. Then the central Italian states joined the kingdom of Italy, although Savoy and Nice were to be ceded to France. With Cavour's approval Garibaldi overthrew the Neapolitan monarchy, but Cavour occupied part of the Papal States which, with Naples and Sicily, were annexed to Italy, to prevent Garibaldi from marching on Rome.
