To the west of Italy, the Fascists claimed that the territories of Corsica, Nice and Savoy held by France were Italian lands. During the period of Italian unification in 1860 to 1861, Prime Minister of Piedmont-Sardinia, Camillo Benso, Count of Cavour, who was leading the unification effort, faced opposition from French Emperor Napoleon III who indicated that France would oppose Italian unification unless France was given Nice and Savoy that were held by Piedmont-Sardinia, as France did not want a powerful state having control of all the passages of the Alps. As a result, Piedmont-Sardinia was pressured to concede Nice and Savoy to France in exchange for France accepting the unification of Italy. The Fascist regime produced literature on Corsica that presented evidence of the "italianità" (Italianness) of the island. The Fascist regime produced literature on Nice that justified that Nice was an Italian land based on historic, ethnic and linguistic grounds. The Fascists quoted Medieval Italian scholar Petrarch who said: "The border of Italy is the Var; consequently Nice is a part of Italy". The Fascists quoted Italian national hero Giuseppe Garibaldi who said: "Corsica and Nice must not belong to France; there will come the day when an Italy mindful of its true worth will reclaim its provinces now so shamefully languishing under foreign domination". Mussolini initially pursued promoting annexation of Corsica through political and diplomatic means, believing that Corsica could be annexed to Italy through first encouraging the existing autonomist tendencies in Corsica and then independence of Corsica from France, that would be followed by annexation of Corsica into Italy.
