The Niçard exodus (esodo nizzardo ˈɛːzodo nitˈtsardo; exode niçois ɛɡzɔd niswa) was one of the first emigration phenomena that involved the Italian populations in the contemporary age. It was due to the refusal of a quarter of the Niçard Italians to stay in Nice after its annexation to France in 1861, which was decided after the Plombières Agreement. The exodus took place starting from 1861, concomitantly and following the annexation of Nice and its surroundings from the Kingdom of Sardinia to France. After the Treaty of Turin was signed in 1860 between the Sardinian king and Napoleon III as a consequence of the Plombières Agreement, the county of Nice was ceded to France as a territorial reward for French assistance in the Second Italian War of Independence against Austria, which saw Lombardy united with Piedmont-Sardinia. King Victor-Emmanuel II, on April 1, 1860, solemnly asked the population to accept the change of sovereignty, in the name of Italian unity, and the cession was ratified by a regional referendum. Italophile manifestations and the acclamation of an “Italian Nice” by the crowd are reported on this occasion. These manifestations could not influence the course of events. A plebiscite was voted on April 15 and April 16, 1860. The opponents of annexation called for abstention, hence the very high abstention rate. The “yes” vote won 83% of registered voters throughout the county of Nice and 86% in Nice, partly thanks to pressure from the authorities. This is the result of a masterful operation of information control by the French and Piedmontese governments, in order to influence the outcome of the vote in relation to the decisions already taken. The irregularities in the plebiscite voting operations were evident. The case of Levens is emblematic: the same official sources recorded, faced with only 407 voters, 481 votes cast, naturally almost all in favor of joining France. The Italian language was the official language of the County, used by the Church, at the town hall, taught in schools, used in theaters and at the Opera, was immediately abolished and replaced by French.
