his south-eastern border and he insisted that if the Kingdom of Sardinia were to keep the new acquisitions they would have to cede Savoy and Nice to France. This was done through the Treaty of Turin, which also called for referendums to confirm the annexation. Subsequently, somewhat controversial referendums showed over 99.5% majorities in both areas in favour of joining France. In 1860, Giuseppe Garibaldi started his campaign to conquer the southern Apennines in the name of the Kingdom of Sardinia. He quickly toppled the Kingdom of the Two Sicilies, which was the largest of the states in the region, stretching from Abruzzo and Naples on the mainland to Messina and Palermo on Sicily. He then marched to Gaeta in the central peninsula. Cavour was satisfied with the unification, while Garibaldi, who was too revolutionary for the king and his prime minister, wanted to conquer Rome as well. Garibaldi was disappointed in this development, as well as in the loss of his home province, Nice, to France. He also failed to fulfill the promises that had gained him popular and military support by the Sicilians: that the new nation would be a republic, not a kingdom, and that the Sicilians would see great economic gains after unification. The former did not come to pass until 1946. Towards the Kingdom of Italy 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. The result was 54.3% in favor of the Republic. Currency The currency in use in Savoy was the Piedmontese scudo. During the Napoleonic era, it was replaced in general circulation by the French franc. In 1816, after regaining their mainland domains, the scudo was replaced by the Sardinian lira, which
