Unification of Italy in the context of "Papal state"

Turin (/tjʊəˈrɪn, ˈtjʊərɪn/ ture-IN, TURE-in, Piedmontese: [tyˈriŋ] ; Italian: Torino [toˈriːno] ; Latin: Augusta Taurinorum, then Taurinum) is a city and an important business and cultural centre in northern Italy. It is the capital city of the Piedmont region and of the Metropolitan City of Turin. From 1861 to 1865, it was the first capital of the Kingdom of Italy. The city is mainly on the western bank of the River Po, below its Susa Valley, and is surrounded by the western Alpine arch and Superga hill. The population of the city proper is 856,745 as of 2025, while the population of the urban area is estimated by Eurostat to be 1.7 million inhabitants. The Turin metropolitan area is estimated by the OECD to have a population of 2.2 million.

The city was historically a major European political centre. From 1563, it was the capital of the Duchy of Savoy, then of the Kingdom of Sardinia ruled by the House of Savoy, and the first capital of the Kingdom of Italy from 1861 to 1865. Turin is sometimes called "the cradle of Italian liberty" for having been the political and intellectual centre of the Risorgimento that led to the unification of Italy, as well as the birthplace of notable individuals who contributed to it, such as Camillo Benso, Count of Cavour.

The Papal States (/ˈpeɪpəl/ PAY-pəl; Italian: Stato Pontificio; Latin: Dicio Pontificia), officially the State of the Church, were a conglomeration of territories on the Italian peninsula under the direct sovereign rule of the pope from 756 to 1870. They were among the major states of Italy from the 8th century until the unification of Italy, which took place between 1859 and 1870, culminating in their demise.

The state was legally established in the 8th century when Pepin the Short, king of the Franks, gave Pope Stephen II, as a temporal sovereign, lands formerly held by Arian Christian Lombards, adding them to lands and other real estate formerly acquired and held by the bishops of Rome as landlords from the time of Constantine onward. This donation came about as part of a process whereby the popes began to turn away from the Byzantine emperors as their foremost temporal guardians for reasons such as increased imperial taxes, disagreement with respect to iconoclasm, and failure of the emperors, or their exarchs in Italy, to protect Rome and the rest of the peninsula from barbarian invasion and pillage.

The Expedition of the Thousand (Italian: Spedizione dei Mille) was an event of the unification of Italy that took place in 1860. A corps of volunteers led by Giuseppe Garibaldi sailed from Quarto al Mare near Genoa and landed in Marsala, Sicily, in order to conquer the Kingdom of the Two Sicilies, ruled by the Spanish House of Bourbon-Two Sicilies. The name of the expedition derives from the initial number of participants, which was around 1,000 people.

The Garibaldians, with the contribution of southern volunteers and reinforcements to the expedition, increased in number, creating the Southern Army. After a campaign of a few months with some victorious battles against the Bourbon army, the Thousand and the newborn southern army managed to conquer the entire Kingdom of the Two Sicilies. The expedition was a success and concluded with a plebiscite that brought Naples and Sicily into the Kingdom of Piedmont-Sardinia, the last territorial conquest before the proclamation of the Kingdom of Italy on 17 March 1861. The Expedition of the Thousand was the only desired action that was jointly decided by the four "Fathers of the Fatherland": Giuseppe Mazzini, Giuseppe Garibaldi, King Victor Emmanuel II, and Camillo Benso, Count of Cavour, pursuing divergent goals. Mazzini, of republican political belief, wanted to liberate Southern Italy and Rome, while Garibaldi wanted to conquer, in the name of Victor Emmanuel II, the Kingdom of the Two Sicilies and continue towards Rome to complete the Italian unification, while Cavour wanted to prevent the conquest of Rome to avoid a conflict with his French ally, Napoleon III, who protected the Papal States.

Giuseppe Maria Garibaldi (/ˌɡærɪˈbɑːldi/ GARR-ib-AHL-dee, Italian: [dʒuˈzɛppe ɡariˈbaldi] ; 4 July 1807 – 2 June 1882) was an Italian general, revolutionary and republican. He contributed to the Unification of Italy (Risorgimento) and the creation of the Kingdom of Italy. He is considered to be one of Italy's "fathers of the fatherland", along with Camillo Benso di Cavour, King Victor Emmanuel II and Giuseppe Mazzini. Garibaldi is also known as the "Hero of the Two Worlds" because of his military enterprises in South America and Europe.

Garibaldi was a follower of the Italian nationalist Mazzini and embraced the republican nationalism of the Young Italy movement. He became a supporter of Italian unification under a democratic republican government. However, breaking with Mazzini, he pragmatically allied himself with the monarchist Cavour and Kingdom of Sardinia in the struggle for independence, subordinating his republican ideals to his nationalist ones until Italy was unified. After participating in an uprising in Piedmont, he was sentenced to death, but escaped and sailed to South America, where he spent 14 years in exile, during which he took part in several wars and learned the art of guerrilla warfare. In 1835 he joined the rebels known as the Ragamuffins (farrapos), in the Ragamuffin War in Brazil, and took up their cause of establishing the Riograndense Republic and later the Catarinense Republic. Garibaldi also became involved in the Uruguayan Civil War, raising an Italian force known as Redshirts, and is still celebrated as an important contributor to Uruguay's reconstitution.

Italy, up until its unification in 1861, was a conglomeration of city-states, republics, and other independent entities. The following is a list of the various Italian states during that period. Following the fall of the Western Roman Empire and the arrival of the Middle Ages (in particular from the 11th century), the Italian Peninsula was divided into numerous states. Many of these states consolidated into major political units that balanced the power on the Italian Peninsula: the Papal States, the Venetian Republic, the Republic of Florence, the Duchy of Milan, the Kingdom of Naples and the Kingdom of Sicily. Unlike all the other Italian states of the medieval and early modern period, the republics of Venice and Genoa, thanks to their maritime power, went beyond territorial conquests within the Italian Peninsula, conquering various regions across the Mediterranean and Black Seas.

The Kingdom of Italy (Italian: Regno d'Italia, pronounced [ˈreɲɲo diˈtaːlja]) was a unitary state that existed from 17 March 1861, when Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 10 June 1946, when the monarchy was abolished, following civil discontent that led to an institutional referendum on 2 June 1946. This resulted in a modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the Risorgimento. That process was influenced by the Savoy-led Kingdom of Sardinia, which was one of Italy's legal predecessor states. In 1882 it became a colonial empire, establishing the Italian Empire.

In 1866, Italy declared war on Austria in alliance with Prussia and, upon its victory, received the region of Veneto. Italian troops entered Rome in 1870, ending more than one thousand years of Papal temporal power. In the last two decades of the 19th century, Italy developed into a colonial power, and in 1882 it entered into a Triple Alliance with the German Empire and the Austro-Hungarian Empire, following strong disagreements with France about their respective colonial expansions. Although relations with Berlin became very friendly, the alliance with Vienna remained purely formal, due in part to Italy's desire to acquire Trentino and Trieste from Austria-Hungary. As a result, Italy accepted the British invitation to join the Allied Powers during World War I, as the western powers promised territorial compensation (at the expense of Austria-Hungary) for participation that was more generous than Vienna's offer in exchange for Italian neutrality. Victory in the war gave Italy a permanent seat in the Council of the League of Nations, but it did not receive all the territories it was promised.

The Italian diaspora (Italian: emigrazione italiana, pronounced [emiɡratˈtsjoːne itaˈljaːna]) is the large-scale emigration of Italians from Italy.

There were two major Italian diasporas in Italian history. The first diaspora began around 1880, two decades after the Unification of Italy, and ended in the 1920s to the early 1940s with the rise of Fascist Italy. Poverty was the main reason for emigration, specifically the lack of land as mezzadria sharecropping flourished in Italy, especially in the South, and property became subdivided over generations. Especially in Southern Italy, conditions were harsh. From the 1860s to the 1950s, Italy was still a largely rural society with many small towns and cities having almost no modern industry and in which land management practices, especially in the South and the Northeast, did not easily convince farmers to stay on the land and to work the soil. Another factor was related to the overpopulation of Italy as a result of the improvements in socioeconomic conditions after Unification. That created a demographic boom and forced the new generations to emigrate en masse in the late 19th century and the early 20th century, mostly to the Americas. The new migration of capital created millions of unskilled jobs around the world and was responsible for the simultaneous mass migration of Italians searching for "bread and work" (Italian: pane e lavoro, pronounced [ˈpaːne e llaˈvoːro]).

In the Roman Empire, Mare Nostrum was a term that referred to the Mediterranean Sea. Meaning "Our Sea" in Latin, it denoted the body of water in the context of borders and policy; Rome remains the only state in history to have controlled the entire Mediterranean coast. The phrase would have been pronounced [ˈma.rɛ ˈnɔs.t̪rʊ̃ː] in Classical Latin, while it is pronounced [ˈmaː.rɛ ˈnɔs.t̪rum] in Ecclesiastical Latin.

The concept of "Mare Nostrum" is noteworthy for having risen to political significance after the unification of Italy in the 19th century, particularly among Italian nationalists and classical fascists, who attempted to revive the term with the connotation of Italy (and the Italian Empire shortly thereafter) being Rome's successor.

The Third Italian War of Independence (Italian: Terza guerra d'indipendenza italiana) was a war between the Kingdom of Italy and the Austrian Empire fought between June and August 1866. The conflict paralleled the Austro-Prussian War and resulted in Austria giving the region of Venetia (present-day Veneto, Friuli and the city of Mantua, the last remnant of the Quadrilatero) to the Second French Empire (acting as intermediary in negotiations), which formally gave it to Italy. Italy's acquisition of this wealthy and populous territory, annexed with a plebiscite, represented a major step in the Unification of Italy.
