Kingdom of Sardinia
On 17 March 1861, law no. 4671 of the Sardinian Parliament proclaimed the Kingdom of Italy, so ratifying the annexations of all other Apennine states, plus Sicily, to the Kingdom of Sardinia. The institutions and laws of the Kingdom were quickly extended to all of Italy, abolishing the administrations of the other regions. Piedmont became the most dominant and wealthiest region in Italy and the capital of Piedmont, Turin, remained the Italian capital until 1865, when the capital was moved to Florence. But many revolts exploded throughout the peninsula, especially in southern Italy, and on the island of Sicily, because of the perceived unfair treatment of the south by the Piedmontese ruling class. The House of Savoy ruled Italy until 1946 when Italy was declared a republic by referendum. In this referendum the southern regions, including Sardinia, voted overwhelmingly in favor of the House of Savoy, with the results being 63.8% in favor of maintaining the monarchy.
Sazan Island
Italy in turn occupied it on 30 October 1914, and established a military commander on the island, which is called Saseno in Italian. This was later ratified on 26 April 1915 by the secret Treaty of London. After World War I, Albania formally ceded the island to Italy on 2 September 1920 as part of the Albano-Italian protocol. The island was part of Italy from 1920 until World War II, it was administratively part of Lagosta, inside the Italian Province of Zara. In those years the Italian authorities built a lighthouse and some naval fortifications, and populated the island with a few families of fishermen relocated from Apulia. The island was united to the Italian Governatorate of Dalmatia in 1941 during World War II and ceded to Albania on 10 February 1947, under the postwar peace treaty with Italy.
