Camillo Benso, Count of Cavour in the context of "Centre-left"

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 Unification of Italy (Italian: Unità d'Italia [uniˈta ddiˈtaːlja]), also known as the Risorgimento (Italian: [risordʒiˈmento]; lit. 'Resurgence'), was the 19th century political and social movement that in 1861 ended in the annexation of various states of the Italian peninsula and its outlying isles to the Kingdom of Sardinia, resulting in the creation of the Kingdom of Italy. Inspired by the rebellions in the 1820s and 1830s against the outcome of the Congress of Vienna, the unification process was precipitated by the Revolutions of 1848, and reached completion in 1870 after the capture of Rome and its designation as the capital of the Kingdom of Italy.

Individuals who played a major part in the struggle for unification and liberation from foreign domination included King Victor Emmanuel II; politician, economist and statesman Camillo Benso, Count of Cavour; general Giuseppe Garibaldi; and journalist and politician Giuseppe Mazzini. Borrowing from the old Latin title Pater Patriae of the Roman emperors, the Italians gave to King Victor Emmanuel II the epithet of Father of the Fatherland (Italian: Padre della Patria). Even after 1870, many ethnic Italian-speakers (Italians in Trentino-Alto Adige/Südtirol, Savoyard Italians, Corfiot Italians, Niçard Italians, Swiss Italians, Corsican Italians, Maltese Italians, Istrian Italians, and Dalmatian Italians) remained outside the borders of the Kingdom of Italy, planting the seeds of Italian irredentism.

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.

Victor Emmanuel II (Italian: Vittorio Emanuele II; full name: Vittorio Emanuele Maria Alberto Eugenio Ferdinando Tommaso di Savoia; 14 March 1820 – 9 January 1878) was King of Sardinia (also informally known as Piedmont–Sardinia) from 23 March 1849 until 17 March 1861, when he assumed the title of King of Italy and became the first king of an independent, united Italy since the 6th century, a title he held until his death in 1878. Borrowing from the old Latin title Pater Patriae of the Roman emperors, the Italians gave him the epithet of "Father of the Fatherland" (Italian: Padre della Patria).

Born in Turin as the eldest son of Charles Albert, Prince of Carignano, and Maria Theresa of Austria, Victor Emmanuel fought in the First Italian War of Independence (1848–1849) before being made King of Sardinia following his father's abdication. He appointed Camillo Benso, Count of Cavour, as his Prime Minister, and he consolidated his position by suppressing the republican left. In 1855, he sent an expeditionary corps to side with French and British forces during the Crimean War; the deployment of Italian troops to the Crimea, and the gallantry shown by them in the Battle of the Chernaya (16 August 1855) and in the siege of Sevastopol led the Kingdom of Sardinia to be among the participants at the peace conference at the end of the war, where it could address the issue of the Italian unification to other European powers. This allowed Victor Emmanuel to ally himself with Napoleon III, Emperor of France. France then supported Sardinia in the Second Italian War of Independence, resulting in the liberation of Lombardy from Austrian rule; as payment for the help, Victor Emmanuel ceded Savoy and Nice to France.

Massimo Taparelli, Marquess of Azeglio (24 October 1798 – 15 January 1866), commonly called Massimo d'Azeglio (Italian: [ˈmassimo tapaˈrɛlli dadˈdzeʎʎo]), was a Piedmontese-Italian statesman, novelist, and painter. He was Prime Minister of Sardinia for almost three years until succeeded by his rival Camillo Benso, Count of Cavour. A moderate liberal and member of the Moderate Party associated with the Historical Right, d'Azeglio hoped for a federal union between Italian states.

As Prime Minister, d'Azeglio consolidated the parliamentary system, getting the young King Victor Emmanuel II to accept his constitutional status, and worked hard for a peace treaty with Austria. Although himself a Roman Catholic, he introduced freedom of worship, supported public education, and sought to reduce the power of the clergy in local political affairs. As a senator, following the annexation of the United Provinces of Central Italy, d'Azeglio attempted to solve the Roman Question through reconciliation between the Vatican and the new Italian Kingdom. His brother was a Jesuit priest.
