Italian, physician, historian, and statesman of the Risorgimento who did much to bring central Italy into union with the north.

After participating in the revolutionary uprisings of 1831, Farini received his medical degree at Bologna and went into practice. Exiled from the Papal States and from Tuscany, he drafted the manifesto of the Rimini movement (1845), which aimed at forcing the papacy to institute reforms. When this movement failed, Farini became the private physician of Prince Jérôme Bonaparte and traveled about Europe.

Under an amnesty granted by the new pope, Pius IX, Farini returned to Italy. He practiced medicine and held several government posts in Rome before leaving in protest of papal policy.

From 1849 to 1865 Farini was a deputy in the Piedmontese legislature at Turin, where he contributed to several journals. In 1850 he wrote the violently antirevolutionary Storia della stato romano dal 1815 al 1850 (“History of the Roman State from 1815 to 1850”). Throughout this period he supported the liberal monarchist Count Camillo Cavour (Cavour, Camillo Benso, conte di (count of)), and together they served in the Cabinet of Massimo d'Azeglio—Farini as minister of public instruction (October 1851–May 1852). A coalition (connubio) of Liberals of the Right Centre and Left Centre parties was arranged by the two men (Feb. 5, 1852) and led directly to Cavour's ascendancy to the premiership.

In 1859 Farini was appointed Piedmontese dictator of Modena (in central Italy) following the outbreak of war with Austria. He established a league of central states (Modena, Tuscany, Romagna, and Parma) for mutual protection. Under Farini's leadership, the league voted to be annexed to Piedmont. Farini gained the approval of Piedmont's ally, Napoleon III of France (August 1860), by assuring him that Rome would not be annexed.

Cavour sent Farini to govern Naples, which had been won for Victor Emmanuel II of Sardinia–Piedmont by Giuseppe Garibaldi. In ill health, Farini ruled badly. On poor terms with the Garibaldians, he resigned and returned to Turin, resuming his post of minister of interior. He became premier of the Kingdom of Italy in December 1862 but resigned four months later because of continuing ill health.
