Udine (US: /ˈuːdiːneɪ/ OO-dee-nay; Italian: [ˈuːdine] ; Friulian: Udin; Latin: Utinum; Slovene: Videm) is a city and comune (municipality) in northeastern Italy, in the middle of the Friuli-Venezia Giulia region, between the Adriatic Sea and the Carnic Alps. It is the capital of the Regional decentralization entity of Udine. Its population was 100,514 in 2012, 176,000 with the urban area.

Udine was first attested in medieval Latin records as Udene in 983 and as Utinum around the year 1000. The origin of the name Udine is unclear. It has been tentatively suggested that the name may be of pre-Roman origin, connected with the Indo-European root *ou̯d- 'udder' used in a figurative sense to mean 'hill'. The Slovene name Videm (with final -m) is a hypercorrection of the local Slovene name Vidan (with final -n), based on settlements named Videm in Slovenia. The Slovene linguist Pavle Merkù characterized the Slovene form Videm as an "idiotic 19th-century hypercorrection."

Udine is the historical capital of Friuli. The area has been inhabited since the Neolithic age.

Based on an old Hungarian legend, Attila (?–453), the leader of the Huns, built a hill there, when besieging Aquileia, because he needed a billet for his winter quarters: he instructed his soldiers to bring soil in their helmets and shields, because the landscape was too flat, without any hill. He established the town there, and built a square tower.

After the fall of the Western Roman Empire, the area increased in importance after the decline of Aquileia, then further after the decline of Cividale. In AD 983 Udine was mentioned for the first time, with the donation of the Utinum castle by emperor Otto II to the Patriarchs of Aquileia, then the main feudal lords of the region. In 1223, with the foundation of the market, the city became finally the most important in the area for economy and trade, and also became the Patriarch's seat.

In 1420, it was conquered by the Republic of Venice. In 1511, it was the seat of a short civil war, which was followed by an earthquake and a plague. Udine remained under Venetian control until 1797, being the second largest city in the state. After the short French domination which ensued, it was part of the Austrian Kingdom of Lombardy-Venetia, and was included in the newly formed Kingdom of Italy in 1866.

During World War I, from May 1915 to October 1917, Udine became the seat of the Italian High Command and was nicknamed "Capitale della Guerra" ("War Capital"). After the battle of Caporetto, it was occupied by the Germans in late 1917 and by the Austro-Hungarians in 1918 until after the Battle of Vittorio Veneto in 1918. After the war it was made capital of a short-lived province (Provincia del Friuli) which included the current provinces of Gorizia, Pordenone and Udine. After September 8, 1943, when Italy surrendered to the Allies in World War II, the city was under direct German administration, which ceased in April 1945.

Udine has a humid subtropical climate (Köppen: Cfa). Precipitation is abundant all year round with spring and autumn being the wettest seasons. The highest temperature recorded was 38.2 °C (101 °F) on July 21, 2006 while the lowest temperature recorded was −18.6 °C (−1 °F) on December 19, 2009.

In 2007, there were 97,880 people residing in Udine itself (whereas the greater area has a population double its size), located in the province of Udine, Friuli-Venezia Giulia, of whom 46.9% were male and 53.1% were female. Minors (children ages 18 and younger) totalled 14.36% of the population; in comparison, to pensioners accounted for 24.27%. This contrasts with the Italian average of 18.06% (minors) and 19.94% (pensioners). The average age of Udine residents is 47 compared to the Italian average of 42. Between 2002 and 2007, the population of Udine grew by 1.48%, whereas Italy as a whole grew by 3.56%.[1] [2] The current birth rate of Udine is 9.13 births per 1,000 inhabitants compared to the Italian average of 9.45 births.

The nearby area close to the border has a Slovene population estimated at 2,000. A 1475 document mentions Slovene as the language of the "lower class" in the town, and the Udine Manuscript of 1458 contains Slovene vocabulary. Alasia da Sommaripa's Italian–Slovenian dictionary was printed in Udine in 1607. However, the Slovenian minority is not officially recognized by the municipality, and Slovene is not taught in any city's state educational institution, nor in neighboring municipalities. Udine, on the other hand, is one of the municipalities in Friuli where Friulian is taught.

As of 2023, 85.30% of the population was of Italian descent. Of the four provincial capitals of the Friuli-Venezia Giulia region, as of 31 December 2022, Udine has the second highest percentage of foreign residents: 14,386 presences or 14.7% of the total population, higher than the regional average of 9.2%.

The old residence of the patriarchs of Aquileia, the palazzo Patriarcale, was erected by Giovanni Fontana in 1517 in place of the older one destroyed by an earthquake in 1511. Under the Austrians it was used as a prison. A recension of the Visigothic code of laws, called the Breviary of Alaric, was formerly preserved In the cathedral archives, in a manuscript known as the Codex Utinensis, which was printed before it was lost.

In the 1550s, Andrea Palladio erected some buildings in Udine. The Oratorio della Purità has 18th-century frescoes by Giambattista Tiepolo and his son Giandomenico.

The church dedicated to St. Mary of the Castle is probably the oldest in Udine, judging from extant fragments dating back to the Lombard era. It lost its parish status in 1263, when it was annexed to the larger parish of Saint'Odorico (now the cathedral). It has been renovated many times over the centuries: the façade, for example, was entirely rebuilt after the 1511 Idrija earthquake. Its three naves preserve the suggestive atmosphere of silence and contemplation, which is often found in old churches. The Venetian Governor, Tommaso Lippomano, commissioned the Venetian Gothic portico with steps and ramps leading down the hill in 1487.

In the principal square (Piazza della Libertà) stands the town hall (Loggia del Lionello) built in 1448–1457 in the Venetian-Gothic style opposite a clock tower (Torre dell'Orologio) resembling that of the Piazza San Marco at Venice. It was begun in 1448 on a project by Nicolò Lionello, a local goldsmith, and was rebuilt following a fire in 1876. The new design was projected by the architect Andrea Scala.

Opposite the Loggia del Lionello is the Loggia di San Giovanni, a Renaissance structure designed by Bernardino da Morcote. Other noteworthy monuments in the square are the Fountain by Giovanni Carrara, an architect from Bergamo (1542); the Columns bearing the Venetian Lion and the Statue of Justice (1614), the statues of Hercules and Cacus and the Statue of Peace (1819) which was donated to Udine by Emperor Francis I to commemorate the peace Treaty of Campoformido.

The Cathedral of Udine is an imposing edifice whose construction started in 1236, on a Latin cross-shaped plan with three naves and chapels along the sides. The church was consecrated in 1335 as Santa Maria Maggiore. At the beginning of the 18th century, a radical transformation project involving both the exterior and the interior was undertaken at the request and expense of the Manin family. The Baroque interior has monumental dimensions and contains many works of art by Tiepolo, Amalteo, and Ludovico Dorigny. On the ground floor of the bell tower (built from 1441 over the ancient baptistry) is a chapel which is completely adorned with frescoes by Vitale da Bologna (1349).

The centre of Udine is dominated by the castle, built by the Venetians from 1517 over a Lombard fortification ruined by an earthquake in 1511. The current Renaissance appearance dates from the intervention of Giovanni da Udine, who finished the works starting from 1547. The castle houses one of the most ancient Parliament Halls of Europe.
