# Leuven

Leuven (UK: /ˈlɜːvən/, US: /ˈlʌvən/, Dutch: ), also called Louvain (/luːˈvæ̃/, US also /luːˈveɪn/, French: ), is the capital and largest city of the province of Flemish Brabant in the Flemish Region of Belgium. It is located about 25 kilometres (16 miles) east of Brussels. The municipality itself comprises the sub-municipalities of Heverlee, Kessel-Lo, Leuven proper, Wilsele, Wijgmaal and part of Haasrode and Korbeek-Lo. It is the eighth largest city in Belgium, with more than 100,244 inhabitants.
Leuven has been a university city since 1425. This makes it the oldest university city in the Low Countries. KU Leuven, the largest Dutch-speaking university in the world and the largest university in the Low Countries (and thus also Belgium's largest university), has its flagship campus in Leuven.
The city is home of the headquarters of Anheuser-Busch InBev, the world's largest beer brewer and sixth-largest fast-moving consumer goods company.

## History
### Middle Ages

The earliest mention of Leuven (Loven) dates from 891, when a Viking army was defeated by the Frankish king Arnulf of Carinthia (see: Battle of Leuven). According to a legend, the city's red and white arms depict the blood-stained shores of the river Dyle after this battle, similarly to the flag of Austria and the flag of Latvia.
Situated beside this river, and near to the stronghold of the Dukes of Brabant, Leuven became the most important centre of trade in the duchy between the 11th and 14th centuries. A token of its former importance as a centre of cloth manufacture is shown in that ordinary linen cloth was known, in late-14th-century and 15th-century texts, as lewyn (other spellings: Leuwyn, Levyne, Lewan(e), Lovanium, Louvain).

### Early modern period

In the 15th century, a new golden era began with the founding of the largest and oldest university in the Low Countries, the University of Leuven, in 1425. Prestigious buildings like the Town Hall and the Saint Peter's Church (itself designated a UNESCO World Heritage Site in 1999) were constructed. The art of painting flourished with painters such as Dirk Bouts, Albrecht Bouts and Jan Rombouts the Elder. The painter Quinten Metsys was born and trained in Leuven.
By the turn of the 16th century, Leuven had become a major European center for art and knowledge with humanists like Erasmus and Hieronymus van Busleyden working there. In 1517 the latter founded the Collegium Trilingue in which the three ancient languages: Latin, Greek and Hebrew were taught. It promoted the critical study of classical literature and the Bible. Thomas More published his Utopia at Dirk Martens printing house in Leuven in 1516. Gemma Frisius laid the foundation for modern triangulation methods and cartography. He further made important contributions to mathematics, geography and astronomy. Gerardus Mercator and John Dee were among his students. Leuven became a leading centre for the fabrication of precision astronomical instruments, such as the planetaria and the terrestrial and celestial globes built by Gaspard van der Heyden and Gualterus Arsenius. Andreas Vesalius completed his medicine studies in Leuven, before moving to Padova and Basel. Religious persecutions of Protestants, followed by greater religious and political turmoil starting in the late 1560s, greatly affected intellectual life in Leuven. Many professors and alumni from Leuven moved abroad. The newly founded University of Leiden in Holland, amongst others, would profit greatly from this brain drain. Despite this the university continued to excel in disciplines like theology with Johannes Molanus and classical studies with Justus Lipsius.

### 18th and 19th centuries

In the 18th century, the brewery Den Horn (meaning "the horn") flourished. In 1708, Sebastien Artois became the master brewer at Den Horn, and gave his name to the brewery in 1717, now part of AB InBev, whose flagship beer, Stella Artois, is brewed in Leuven and sold in many countries.
Leuven developed considerably during the 19th century. Dozens of squares were created, including the Sint-Jacobsplein, the Volksplaats (today's Ladeuzeplein) and the Statieplein (today's Martelarenplein). From 1835, the streets of the city were lit with gas. The Voer stream was vaulted, the channels occupying the middle of the streets were removed, a number of narrow streets were widened or simply destroyed and a considerable number of sewers were installed. The municipal theatre and the main post office were built, respectively in 1866 and between 1893 and 1895. It was also at this time that the central prison was built.

### 20th century
#### World War I

Leuven has several times been besieged or occupied by foreign armies; these include the Battle of Leuven (891), the Siege of Leuven (1635) and the Battle of Leuven (1831). In the 20th century, both world wars inflicted major damage upon the city. Upon Germany's entry into World War I, the town was heavily damaged by rampaging soldiers. In all, about 300 civilians died. The university library was destroyed on 25 August 1914, using petrol and incendiary pastilles. Approximately 230,000 volumes were lost in the destruction, including Gothic and Renaissance manuscripts, a collection of 750 medieval manuscripts, and more than 1,000 incunabula (books printed before 1501). The German atrocities and the cultural destruction caused worldwide outrage. The burning of the city was done as a reprisal, which at the time was legal under international law, as the Germans alleged that Belgian civilians had taken part in the fighting and killed German troops. The old library building was rebuilt after the war, and much of the collection was replaced. A new, dedicated Central Library was built on the square now known as Ladeuzeplein; it was officially opened on 4 July 1928.

#### World War II

In World War II, after the start of the German offensive, Leuven formed part of the British Expeditionary Force's front line and was defended by units of the 3rd Division and Belgian troops. From 14 to 16 May 1940, the German Army Group B assaulted the city with heavy air and artillery support. The British withdrew their forces to the River Senne on the night of 16 May and the town was occupied the next day. The new university library building was set on fire by shelling, on 16 May, and nearly a million books were lost.

## Economy

Given the presence of the KU Leuven, Europe's most innovative university according to Reuters, much of the local economy is concentrated on spin-offs from academic research. In addition, the Leuven-based research centre, IMEC, is a research centre in the field of nano-electronics and digital technologies. As a result, dozens of companies in high technological fields such as biotech, robotics, additive manufacturing and IT, are located near these research institutes on the Arenberg Science Park and Haasrode Research-Park. Quite a few international companies such as Siemens, Huawei, Nitto Denko, JSR Corporation or Commscope have important, often research oriented branches, in Leuven. The academic hospital UZ Leuven, first in Europe regarding the number of clinical tests per capita and approval rates for clinical trials, UZ Leuven is another advanced research institute. It is one of Europe's largest academic hospitals. As a result, large numbers of private service providers are active in the medical, financial and legal fields.
