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.
[3] 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 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.
Giuseppe Garibaldi, born in Nice, tenaciously opposed the cession of his hometown to France, arguing that the Plebiscite he ratified in the treaty was vitiated by electoral fraud.
The French government sends 10,000 soldiers to Nice, closes the Italian newspaper Il Diritto di Nizza and imprisons several demonstrators.
On February 13, Garibaldi was not allowed to speak at the French parliament meeting in Bordeaux to ask for the reunification of Nice to the newborn Italian unitary state, and he resigned from his post as deputy.
[12] The failure of Vespers led to the expulsion of the last pro-Italian intellectuals from Nice, such as Luciano Mereu or Giuseppe Bres, who were expelled or deported.
Many intellectuals from Nice took refuge in Italy, such as Giovan Battista Bottero who took over the direction of the newspaper La Gazzetta del Popolo in Turin.
