Massimo Taparelli, Marquess of Azeglio, commonly called Massimo d'Azeglio, was a Piedmontese-Italian statesman, novelist, and painter. He was Prime Minister of Sardinia for almost three years until succeeded by his rival Camillo Benso, Count of Cavour. D'Azeglio was a moderate liberal and member of the Moderate Party associated with the Historical Right. He hoped for a federal union between Italian states.

Camillo Paolo Filippo Giulio Benso, Count of Cavour, Isolabella and Leri, generally known as the Count of Cavour or simply Cavour, was an Italian politician, businessman, economist and noble, and a leading figure in the movement towards Italian unification. He was one of the leaders of the Historical Right and Prime Minister of the Kingdom of Sardinia, a position he maintained throughout the Second Italian War of Independence and Giuseppe Garibaldi's campaigns to unite Italy. After the declaration of a united Kingdom of Italy, Cavour took office as the first Prime Minister of Italy; he died after only three months in office and did not live to see the Roman Question solved through the complete unification of the country after the Capture of Rome in 1870.
