Count Cavour

Count Camillo Benso di Cavour, born in Turin in 1810, served as Prime Minister of the Kingdom of Piedmont-Sardinia under King Victor Emmanuel II and is regarded as the principal architect of Italian unification (the Risorgimento). A liberal-conservative monarchist rather than a republican revolutionary, Cavour pursued unification through realpolitik — calculated diplomacy, secret alliances and limited war — rather than the popular insurrection favoured by Giuseppe Mazzini or the volunteer campaigns of Giuseppe Garibaldi. He founded the newspaper Il Risorgimento in 1847, entered the Piedmontese cabinet, and became premier in 1852, modernising the kingdom's economy, railways, banking and army to make Piedmont the nucleus of a future Italy.

Cavour's method rested on harnessing great-power rivalry. He committed Piedmont to the Crimean War (1855) alongside Britain and France, securing a seat at the Congress of Paris (1856) where he internationalised the "Italian question." His decisive stroke was the secret Pact of Plombières (July 1858) with Napoleon III, by which France agreed to aid Piedmont against Austria in exchange for Nice and Savoy. The resulting Second War of Italian Independence (1859) brought victories at Magenta and Solferino, but Napoleon III's unilateral Armistice of Villafranca enraged Cavour, prompting his temporary resignation. Piedmont nonetheless absorbed Lombardy, and plebiscites in 1860 annexed Tuscany, Parma, Modena and the Romagna, formalised by the Treaty of Turin ceding Nice and Savoy to France.

When Garibaldi's "Expedition of the Thousand" (1860) toppled the Bourbon Kingdom of the Two Sicilies, Cavour shrewdly dispatched Piedmontese forces through the Papal States to intercept the radical advance, ensuring the south was annexed to the monarchy rather than becoming a republic. The Kingdom of Italy was proclaimed on 17 March 1861 with Victor Emmanuel II as king and Cavour as its first prime minister. He died only months later, in June 1861, with Rome (under French protection until 1870) and Venetia (Austrian until 1866) still outside the new state. His pragmatic dictum on church-state relations — "a free church in a free state" — and his manipulation of diplomacy made him the counterpoint to Mazzini's "soul" and Garibaldi's "sword."

For UPSC World History (General Studies Paper I and the optional), Cavour is a high-frequency figure tested on the unification of Italy alongside Mazzini, Garibaldi and Victor Emmanuel II. Typical question angles compare the three architects' contrasting methods (idealism versus realpolitik versus military adventurism), ask candidates to sequence the key events (Plombières 1858, war of 1859, Villafranca, plebiscites of 1860, proclamation of 1861), and probe the role of Napoleon III and the Crimean War in internationalising Italian nationalism. Cavour is frequently paired with Otto von Bismarck in comparative questions on nineteenth-century nation-building through diplomacy and "blood and iron," making mastery of his strategy essential for both world-history and comparative-politics segments.
