Northern Italy

Ancient peoples of Northern Italy, with Celtic peoples shown in blue.

In pre-Roman centuries it was inhabited by different peoples among whom the Ligures, the ancient Veneti, who prospered through their trade in amber and breeding of horses, the Etruscans, who colonized Northern Italy from Tuscany, founded the city of Bologna and spread the use of writing; later, starting from the 5th century BC, the area was invaded by Celtic – Gallic tribes. These people founded several cities like Turin and Milan and extended their rule from the Alps to the Adriatic Sea. Their development was halted by the Roman expansion in the Po Valley from the 3rd century BC onwards. After centuries of struggle, in 194 BC the entire area of what is now Northern Italy became a Roman province with the name of Gallia Cisalpina ("Gaul on the inner side (with respect to Rome) of the Alps"). The Roman culture and language overwhelmed the former civilization in the following years, and Northern Italy became one of the most developed and rich areas of the western half of the empire with the construction of a wide array of roads and the development of agriculture and trade.

In late antiquity the strategic role of Northern Italy was emphasized by the moving of the capital of the Western Empire from Rome to Mediolanum in 286 and later to Ravenna from 402 until the empire collapsed in 476.

Migration of the Lombards towards Northern Italy

After the fall of the Western Empire, Northern Italy suffered heavily from destruction brought about by migration from Germanic peoples and from the Gothic War. In the 570s the Germanic Lombards, or Longobardi, entered Northern Italy from Friuli and founded a long-lasting reign (with its capital in Pavia) that gave the medieval name to the whole Northern Italy and the current name to the Lombardy region. After the initial struggles, relationships between the Lombard people and the Latin-speaking people improved. In the end, the Lombard language and culture assimilated with the Latin culture, leaving evidence in many names, the legal code and laws, and other things. The end of Lombard rule came in 774, when the Frankish king Charlemagne conquered Pavia, deposed Desiderius, the last Lombard king, and annexed the Lombard Kingdom to his empire changing the name in Kingdom of Italy. The former Lombard dukes were mostly replaced by Frankish counts, prince-bishops or marquises.

Member cities of the first and second Lombard League.

In the 10th century most of Northern Italy was formally under the rule of the Holy Roman Empire but was in fact divided in a multiplicity of small, autonomous city-states, the medieval communes and maritime republic. The 11th century marked a significant boom in Northern Italy's economy, due to improved trading and agricultural innovations, culture flourished as well with many universities founded, among them the University of Bologna, the oldest university in Europe. The increasing richness of the city-states made them able to defy the traditional feudal supreme power, represented by the German emperors and their local vassals. This process led to the creation of different Lombard Leagues formed by allied cities of Lombardy that defeated the Hohenstaufen Emperor Frederick I, at Legnano, and his grandson Frederick II, at Parma, and becoming virtually independent from the German emperors.

The Leagues failed to develop from an alliance to a lasting confederation and subsequently, among the various local city-states, a process of consolidation took place; most of them became lordships ruled by powerful families like the Della Scala of Verona or the Visconti of Milan, and conquered neighboring cities threatening to unify Northern Italy under a single state.

Northern Italy after the Peace of Lodi

In the end a balance of power was reached in 1454 with the Peace of Lodi and Northern Italy ended up divided between a small number of regional states, the most powerful were the Duchies of Savoy, Milan, Mantua, Ferrara and the Republics of Genoa and Venice, which had begun to extend its influence in the mainland from the 14th century onwards.

In the 15th century Northern Italy became one of the centres of the Renaissance whose culture and works of art were highly regarded. The enterprising class of the communes extended its trade and banking activities well into northern Europe and "Lombards", the term that designated the merchants or bankers coming from northern Italy, were present in all of Europe. The Italian Wars between 1494 and 1559 ended the North Italian Renaissance and brought the region to be fought between France and the Spanish and Austrian House of Habsburg. After the war, most of the present-day Lombardy became under direct or indirect control of Spain. At the same time Ottoman control of the eastern Mediterranean and the discoveries of sea routes to Asia around Africa and of the Americas led to the decline of the Venetian Republic. While the Republic of Genoa managed to become the main banking base of the Spanish Empire.[6]

Pestilences, like that of 1628/1630, and the generally declining conditions of Italy's economy in the 17th and 18th centuries halted the further development of Northern Italy. The only polity that managed to thrive in this period was the Savoy's state which, thanks to military and diplomatic victories in 1720, managed to acquire the island of Sardinia, through which the then Dukes gained legitimacy as a proper Kingdom and increased Turin's importance as a European capital.

The Iron Crown of Lombardy, used by Napoleon to symbolize authority over Northern Italy

After the French Revolution in the late 18th century Northern Italy was conquered by the French armies, many client republics were created by Napoleon and in 1805 a new Kingdom of Italy, made of all of Northern Italy but Piedmont that was annexed to France, was established with Milan as capital and Napoleon as head of state. In the congress of Vienna, the Kingdom of Sardinia was restored, and furthermore enlarged by annexing the Republic of Genoa to strengthen it as a barrier against France. The rest of Northern Italy was under Austrian rule, either direct like in the Lombardo-Venetian Kingdom or indirect like in the Duchies of Parma and Modena. Bologna and Romagna were given to the Papal State.

The Austrian imperial government was unpopular because of their anti-liberal politics and Northern Italy became the intellectual centre leading the Italian unification process. Piedmont and the Kingdom of Sardinia, in particular, was the state that launched Italy's unification in 1859–1861. After defeating the Austrians in 1859 and annexing Northern Italy the new state proceeded to launch a campaign to conquer Southern and Central Italy and Turin briefly became the capital of the almost whole of Italy.

Anti-Fascist Partisans in the streets of Bologna after the general insurrection of April 1945

After Italian unification the capital was moved from Turin to Rome and the administrative and institutional importance of Northern Italy was deeply reduced. However, from the late 19th century and especially with the economic boom of the 1950s–1960s, Northern Italy and especially the cities of Turin, Genoa, and Milan was the most important region in the Italian industrialization and sharpened its status of richest and most industrialized part of Italy. Between 1943 and 1945, during the Second World War, Northern Italy was part of the Fascist Italian Social Republic and the main theatre of the anti-fascist partisan activity. Between April 19 and 25, 1945 the cities of Northern Italy began an insurrection against Fascist and Nazist forces that led to the liberation of Northern Italy by Allied forces Economic differences between Northern Italy and the rest of the country, as well as the short history of Italy as a single nation, led in the 1990s to the emergence of Padanian nationalism, as Lega Nord promoted either secession or larger autonomy for Padania, the name chosen to represent Northern Italy.

Alpine lakes like Lake Garda are characterised by warmer microclimates than the surrounding areas

The climate of Northern Italy is mainly humid subtropical (Köppen Cfa), especially in the plains. Winter in Northern Italy is normally long, relatively dry and rather cold. In addition, there is a high seasonal temperature variation between summer and winter. In the hills and mountains, the climate is humid continental (Köppen Dfb). In the valleys it is cold but usually with low humidity, while it can be severely cold above 1,000 metres (3,300 ft), with copious snowfalls. The coastal areas of Liguria generally fit the Mediterranean climate profile. In the Alpine foothills, characterised by an Oceanic climate (Köppen Cfb), numerous lakes exercise a mitigating influence, allowing the cultivation of typically Mediterranean crops (olives, citrus fruit).

A peculiarity of the regional climate is the thick fog that covers the plains between October and February, especially in the central Po Plain. The east coast, from Romagna to Trieste is occasionally affected by the cold bora winds in winter and spring.

The coldest month is January: the Po valley's mean temperature is between −1 and 1 °C (30 and 34 °F). Winter morning lows can occasionally reach −30 to −20 °C (−22 to −4 °F) in the Alps and −14 to −8 °C (7 to 18 °F) in the Po valley, with records close to −30 °C (−22 °F) near Bologna are some of the coldest winters. Summer is usually more stable, although quite stormy near the Alps, with July temperatures are 22–24 °C (72–75 °F) north of river Po, like in Milan or Venice, and south of river Po can reach 24–25 °C (75–77 °F) like in Bologna.

The number of days with lows below 0 °C (32 °F) is usually from 60 to 90 a year, with peaks of 100–110 days in the mainly rural zones.[7] In the colder winters, the Venice Lagoon may freeze, and in the coldest ones even enough to walk on the ice sheet.[8]

Precipitation evenly distributed during the year, although the summer is usually slightly wetter. is more intense in the Prealpine zone, up to 1,500 to 2,000 mm (59 to 79 inches) annually, but is abundant also in the plains and Alpine zones, with an average of 600 to 850 mm (24 to 33 inches) annually. The total annual rainfall is on average 827 mm (32.6 inches).[9] Snow is quite common between early December and early March in cities like Turin, Milan and Bologna, but sometimes it appears in late November or late March and even April. Both the Alps and the Apennine can see up to 500–1,000 cm (200–390 inches) of snow in a year at 2,000 m (6,600 feet); on the highest peaks of the Alps, snow may fall even during mid summer, and glaciers are present.

Because of high industrialization and the lack of wind due to being closed between mountain ranges air pollution remains a severe problem in Northern Italy. Even if smog levels have decreased dramatically since the 1970s and 1980s, in 2005 a team of researchers at the Royal Netherlands Meteorological Institute reported that Northern Italy was one of Europe's most polluted areas in terms of smog and air pollution due to its climatic and geographic conditions, which cause the stagnation of pollutants.[10]

In March 2019, the European Space Agency (ESA)[11] published images took from their satellites. These images show a big stain, made of nitrogen dioxide and fine particles, situated above the Po Valley area, which incorporates the city of Milan, Turin, and Bologna. Milan and Turin share high levels of ozone and nitrogen oxides, which are mainly produced by cars diesel and petrol engines. The big stain analyzed by ESA is the main reason why Po valley air pollution levels are so high it is considered nowadays the worst area in Europe for air quality. To shed light on how dangerous it is for humans to live in polluted environments, Chicago Energy Policy Institute[12] has recently developed the Air Quality Life Index (AQLI), a system capable of analyzing air pollution worldwide. According to AQLI findings, Po valley air pollution affects inhabitants so hard that it cuts off about half a year of their life expectancy. The main reasons why there's a big stain of air pollution over the Po valley are strictly connected to livestock and factories. The so-called "NPK fertilizers", made of nitrogen, phosphorus and potassium, along with manure emissions from intensive breeding and high levels of nitrogen dioxide released by diesel and petrol engines are all accountable for this disastrous air condition in Northern Italy. The region of Lombardy produces also vast amounts of animal waste, a big contributor to pollution. It delivers more than 40 percent of Italy's milk production, for example, while over half of the Italian pig production is located in the Po Valley.[13]

According to a research, published in The Lancet Planetary Health[14] in January 2021, which estimates the death rate associated with fine particulate matter (PM2.5) and nitrogen dioxide (NO2) pollution in 1000 European cities, Brescia and Bergamo in Lombardy have the highest death rate from fine particulate matter (PM2.5) in Europe. Vicenza (Veneto) and Saronno (Lombardy) are respectively in fourth and eighth place in a top ten of ten cities. Turin and Milan are also at the top of the European ranking – 3rd and 5th respectively – in terms of increased mortality from nitrogen dioxide, a gas that derives mainly from traffic and in particular from diesel vehicles, while Verona, Treviso, Padova, Como and Venice rank eleventh, fourteenth, fifteenth, seventeenth and twentythird respectively.

The data show that many cities in the Po Valley suffer the most serious impact at European level due to poor air quality, first of all the metropolitan area of Milan, thirteenth in the ranking in terms of fine particulate impact, where any year 3967 premature deaths – approximately 9% of the total.

During the Middle Ages, mainly between the thirteenth and fifteenth centuries, an illustrious vulgar was in use, by the name of "Lombard-Venetian koiné". In medieval sources it was simply called "written language" or Lombard, because the toponym "Lombardy" was then used to indicate the entire region of northern Italy.

Starting from the fifteenth century, the Lombard-Venetian koiné began to give ground with respect to the Tuscan, a phenomenon that Tagliavini describes as follows: "Florentine, thanks to (Dante) and other great Tuscans like Petrarch and Boccaccio, to the central position of Florence and to the historical conditions of the time, gradually spread throughout Italy, also resulting in the disappearance of the High-Italian κοινή, which in the thirteenth century had risen to a certain prestige".

This literary koiné manifested itself with authors such as Bonvesin da la Riva, Giacomino da Verona, Uguccione da Lodi, Girardo Patecchio, etc.
