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.
History of Sardinia
From the 8th century BC, Phoenicians founded several cities and strongholds on strategic points in the south and west of Sardinia, often peninsulas or islands near estuaries, easy to defend and natural harbours, such as Tharros, Bithia, Sulci, Nora and Caralis (Cagliari). The majority of the inhabitants in these cities were of indigenous nuragic stock while the Phoenician element was, although culturally predominant, in minority. The Phoenicians came originally from what is now Lebanon and founded a vast trading network in the Mediterranean. Sardinia had a special position because it was central in the Western Mediterranean between Carthage, Spain, the river Rhône and the Etruscan civilization area. The mining area of the Iglesiente was important for the metals lead and zinc. After the Phoenicians, the Carthaginians took over control in this part of the Mediterranean, around 510 BC, after that a first attempt of conquest of the island in 540 BC ends in failure. They expanded their influence to the western and southern coast from Bosa to Caralis, consolidating the existing Phoenician colonies, administered by plenipotentiaries called "Suffetes", and founding new ones such as Olbia, Cornus and Neapolis; Tharros become probably the capital of the province. Carthage stressed the growing of grain and cereals and prohibited fruit trees.
