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
No evidence survives of any warring between the tribes, but the Sicanians moved eastwards when the Elymians settled in the northwest corner of the island. The Sicels are thought to have originated in Liguria; they arrived from mainland Italy in 1200 BC and forced the Sicanians to move back across Sicily and to settle in the middle of the island. Other minor Italic groups who settled in Sicily included the Ausones (Aeolian Islands, Milazzo) and the Morgetes of Morgantina. Studies of genetic records reveal that peoples from various parts of the Mediterranean Basin mixed with the ancient inhabitants of Sicily, including Egyptians and Iberians.
