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 Western civilization
In the city-states of Italy, many argued for a unification of all the Italian kingdoms into a single nation. Obstacles to this included the many Italian dialects spoken by the people of Italy, and the Austrian presence in the north of the peninsula. Unification of the peninsula began in 1859. The powerful Kingdom of Sardinia (also called Savoy or Piedmont) formed an alliance with France and went to war with Austria in that year. The war ended with a Sardinian victory, and Austrian forces left Italy. Plebiscites were held in several cities, and the majority of people voted for union with Sardinia, creating the Kingdom of Italy under Victor Emmanuel II. In 1860, the Italian nationalist Garibaldi led revolutionaries in an overthrow of the government of the Kingdom of the Two Sicilies. A plebiscite held there resulted in a unification of that kingdom with Italy. Italian forces seized the eastern Papal States in 1861. In 1866 Venetia became part of Italy after Italy's ally, Prussia, defeated that kingdom's rulers, the Austrians, in Austro-Prussian War. In 1870, Italian troops conquered the Papal States, completing unification. Pope Pius IX refused to recognize the Italian government or negotiate settlement for the loss of Church land.
