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.
Sicily
The Phoenician settlements in the western part of the island predates the Greeks. From about 750 BC, the Greeks began to live in Sicily (Σικελία – "Sikelia"), establishing many important settlements. The most important colony was in Syracuse; others were located at Akragas, Selinunte, Gela, Himera and Zancle. The native Sicani and Sicel peoples were absorbed into the Hellenic culture with relative ease, and the area became part of "Magna Graecia" along with the rest of southern Italy, which the Greeks had also colonised. Sicily was very fertile, and the successful introduction of olives and grape vines created a great deal of profitable trading. A significant part of Greek culture on the island was that of the Greek religion, and many temples were built throughout Sicily, including several in the "Valley of the Temples" at Agrigento.
