Military history of Italy
The Nobility of Italy comprised individuals and their families of Italy recognized by sovereigns, such as the Holy Roman Emperor, the Holy See, Kings of Italy or certain other Italian kings and sovereigns as members of a class of persons officially enjoying hereditary privileges which distinguished them from other persons and families. They often held lands as fiefs and sometimes were endowed with hereditary titles. Medieval "Italy" was a set of separate states until 1870, and had many royal bloodlines. Italian royal families were often related through marriage to each other and to other European royal families.
Before Italian Unification in the mid-19th century, the existence of the Kingdom of Sardinia, the Kingdom of the Two Sicilies (before 1816: the Kingdom of Naples and the Kingdom of Sicily), the Grand Duchy of Tuscany, the Duchy of Parma, the Duchy of Modena, the Duchy of Savoy, the Duchy of Milan, the Papal States, various republics and the Austrian and French dependencies in Northern Italy led to parallel nobilities with different traditions and rules.
Kingdom of Sardinia
The military history of Italy chronicles a vast time period, lasting from the overthrow of Tarquinius Superbus in 509 BC, through the Roman Empire, Italian unification, and into the modern day. The Italian peninsula has been a centre of military conflict throughout European history.
The Kingdom of Sardinia was a state in Europe from the early 14th century until the mid-19th. It was the predecessor state of today's Italy. A small state with weak institutions when it was acquired by the House of Savoy in 1720, the Savoyards united their insular and continental domains and built Sardinia—often called Piedmont-Sardinia in this period—into one of the great powers by the time of the Crimean War (1853–56). Its final capital was Turin, the centre of Savoyard power since the Middle Ages.
The kingdom initially consisted of the islands of Corsica and Sardinia, sovereignty over both of which was claimed by the Papacy, which granted them as a fief, the regnum Sardiniae et Corsicae ("kingdom of Sardinia and Corsica"), to King James II of Aragon in 1297. Beginning in 1324, James and his successors conquered the island of Sardinia and established de fact their de jure authority. In 1420 the last competing claim to the island was bought out. After the union of the crown of Aragon with that of Castile, Sardinia became a part of the burgeoning Spanish Empire. In 1720 it was ceded by the Habsburg and Bourbon claimants to the Spanish throne to the Duke Victor Amadeus II of Savoy. The kingdom of Sardinia came progressively to be identified with the entire domain ruled by the House of Savoy, which included, besides Savoy and Aosta, dynastic possessions since the 11th century, the Piedmont (a possession built up in the 13th century) and Nice (a possession since 1388). While the traditional capital of Sardinia and seat of its viceroys was Cagliari, the Piedmontese city of Turin was the de facto capital of the House of Savoy.
Camillo Benso, Count of Cavour
Italian unification (Italian: Risorgimento [risordʒiˈmento], meaning the Resurgence) was the political and social movement that agglomerated different states of the Italian peninsula into the single state of the Kingdom of Italy in the 19th century. Despite a lack of consensus on the exact dates for the beginning and end of this period, many scholars agree that the process began in 1815 with the Congress of Vienna and the end of Napoleonic rule, and ended in 1870 with the Capture of Rome. Some of the terre irredente did not, however, join the Kingdom of Italy until after World War I with the Treaty of Saint-Germain. Some nationalists see the Armistice of Villa Giusti as the end of unification.
Camillo Paolo Filippo Giulio Benso, Count of Cavour, of Isolabella and of Leri (August 10, 1810 – June 6, 1861), generally known as Cavour (Italian: [kaˈvur]) was a leading figure in the movement toward Italian unification. He was the founder of the original Liberal Party and Prime Minister of the Kingdom of Piedmont-Sardinia, a position he maintained (except for a six-month resignation) throughout the Second Italian War of Independence and Garibaldi's campaigns to unite Italy. After the declaration of a united Kingdom of Italy, Cavour took office as Italy's first Prime Minister; he died after only three months in office, and thus did not live to see Venetia or Rome as part of the new Italian nation.
Cavour put forth several economic reforms in his native region of Piedmont in his earlier years, and founded the political newspaper Il Risorgimento. After being elected to the Chamber of Deputies, he quickly rose in rank through the Piedmontese government, coming to dominate the Chamber of Deputies through a union of left-center and right-center politicians. After a large rail system expansion program, Cavour became prime minister in 1852. As prime minister, Cavour successfully negotiated Piedmont's way through the Crimean War, Second Italian War of Independence, and Garibaldi's expeditions, managing to maneuver Piedmont diplomatically to become a new great power in Europe, controlling a nearly united Italy that was five times as large as Piedmont had been before he came to power.
