カミッロ・カヴール
In 1860 Camillo Benso, Count of Cavour, one of the architects of Italian unity with the Kingdom of Piedmont-Sardinia, negotiated support for Napoleon III in exchange for Savoy and the County of Nice as set forth in the Treaty of Turin. The annexation was confirmed on 15 and 16 April 1860 by 30,712 male electors enrolled in the 89 communes of the County of Nice who, for the first time, had universal male suffrage by plebiscite. The "Yes" vote for reunification with France was 83.8% of registered voters and 99.2% of votes. The new department of Alpes-Maritimes consisted of the former County of Nice, divided into an Arrondissement of Nice and an Arrondissement of Puget-Théniers (both arrondissements existed in the former Department (1793–1814)), and a portion of the Var department, which formed the Arrondissement of Grasse. However, the County of Nice did not include Tende and La Brigue, which were still part of Piedmont-Sardinia.
