# Catholic University of Leuven (1834–1968)

The Catholic University of Leuven or Louvain (French: Université catholique de Louvain, Dutch: Katholieke Hogeschool te Leuven, later Katholieke Universiteit te Leuven) was founded in 1834 in Mechelen as the Catholic University of Belgium, and moved its seat to the town of Leuven in 1835, changing its name to Catholic University of Leuven. In 1968, it was split into two universities, the Katholieke Universiteit Leuven and the Université catholique de Louvain, following tensions between the Dutch and French-speaking student bodies.

## History
### Founding in Mechelen (1834)

On 8 November 1834, on the basis of authorisation in a papal brief of 13 December 1833, from Pope Gregory XVI, the Belgian bishops founded the Catholic University of Belgium (Latin: Universitas catholica Belgii) in Mechelen. About this first year, it is generally referred to as "Catholic University of Mechelen". The bishops aimed to create a university "to accommodate any doctrine from the Holy Apostolic See and to repudiate anything that does not flow from this august source".
The announcement of the bishops' founding of the new university in Mechelen was met with demonstrations and disturbances in the cities of Ghent, Leuven and Liège.
The first rector was the priest and historian Pierre de Ram.

### Move of the new university to Leuven (1835)

The university was short-lived in Mechelen, as the bishops already moved the university to Leuven on 1 December 1835, where it took the name "Catholic University of Leuven". This outraged Belgian liberal opinion, which depicted it as an attempt to usurp the past of the former Old University of Leuven. It also reinvigorated demands for the foundation of a secular university in Brussels which would lead to the foundation of the Free University of Brussels.

#### Previous universities in Leuven

An earlier University of Leuven was founded in 1425 by John IV, Duke of Brabant and chartered by a papal bull of Pope Martin V. It flourished for hundreds of years as the most prominent university in what would become Belgium, and one of the more prominent in Europe. Once formally integrated into the French Republic, the law of 15 September 1793, had decreed the suppression of all the colleges and universities in France and it was abolished by Decree of the Departement of the Dijle on 25 October 1797.
The region next became part of the United Kingdom of the Netherlands (1815–1830), and William I of the Netherlands founded a new university in 1816 in Leuven as a state university (Dutch: Rijksuniversiteit) which was a secular university and where several professors from the old university continued their teaching. In 1830, the Southern Provinces of the United Kingdom of the Netherlands became the independent state of Belgium. This university was closed in 1835.

#### Relation to the Old University of Leuven

With the closing of the State University of Leuven, the new Catholic University of Mechelen moved its seat to Leuven, adjusted its name and declared itself as a "re-founding" of the 1425 University of Leuven.
This claim to continuity with the older institution was challenged in the courts, with Belgium's highest court issuing rulings (in 1844, 1855 and 1861) that as a matter of law the Catholic University of Leuven was a different institution created under a different charter.
Nonetheless, the Catholic University of Leuven unofficially continued to claim to be a continuation of the older institution in Leuven, in spite of the liberal protests of the time.

### Further history as unified institution (1835–1968)

On 3 November 1859, the Catholic University celebrated the silver jubilee of its foundation. A banquet for more than five hundred guests offered by the students to the Rector and the faculty, took place the 23 November 1859, in the great festival hall of the Music Academy of Louvain.
In the year 1884, the Catholic University of Louvain celebrated solemnly its 50th anniversary.
In 1909, the Catholic University celebrated its 75th anniversary, and struck a medal where for the first time it officially used the French word "réinstallation" (resettlement), and the Dutch word "herstelling" (restoration) beginning of a new "official" history.
In 1914, during World War I, Leuven was looted by German troops. They set fire to a large part of the city, effectively destroying about half of it, including the university library (see below). In the early stages of the war, Allied propaganda capitalized on the German destruction as a reflection on German Kultur.

### Split into two officially new institutions (1962–1970)

From its beginning in 1834, the university provided lectures only in French. Latin was sometimes used in the theology faculty, but it was essentially a French-language institution. Lectures in Dutch, the other official language of Belgium and the language spoken in Leuven, had begun to be provided in 1930 in the Catholic University of Leuven in the meantime.
In 1962, in line with constitutional reforms governing official language use, the French and Dutch sections of the Catholic University became autonomous within a common governing structure. Flemish nationalists continued to demand a division of the university, and Dutch speakers expressed resentment at privileges given to French-speaking academic staff and the perceived disdain by the local French-speaking community for their Dutch-speaking neighbours. At the time, Brussels and Leuven were both part of the officially bilingual and now defunct Province of Brabant; but unlike Brussels, Leuven had retained its Dutch-speaking character. Tensions rose when a French-speaking social geographer suggested in a televised lecture that the city of Leuven should be incorporated into an enlarged bilingual 'Greater-Brussels' region. Mainstream Flemish politicians and students began demonstrating under the slogan Leuven Vlaams – Walen Buiten ("Leuven [is] Flemish – Walloons out"). Student demonstrations escalated into violence throughout the mid-1960s. Student unrest fueled by the history of discrimination against Flemings eventually brought down the Belgian government in February 1968.
The dispute was resolved in June 1968 by turning the Dutch-language section of the university into the independent Katholieke Universiteit Leuven, which remained in Leuven. The French-speaking university, called the Université catholique de Louvain, was moved to a greenfield campus called Louvain-la-Neuve ("New Leuven"), farther south in the French-speaking part of the Province of Brabant. Acrimony about the split was long-lasting. Currently, however, research collaborations and student exchanges between the two "sister universities" take place with increasing frequency.

## Library

The library of the Catholic University dating from 1834 was housed in the University Hall, a building which in its oldest parts dated back to 1317. This was destroyed in August 1914 by invading German forces, with the loss of approximately 230,000 books, 950 manuscripts, and 800 incunabula. Materials lost included the Easter Island tablet bearing Rongorongo text E and the oldest Czech Bible.
After the First World War, a new library was built on the Mgr. Ladeuzeplein, designed by the American architect Whitney Warren in a neo-Flemish-Renaissance style. Construction took place between 1921 and 1928. Its monumental size is a reflection of the Allied victory against Germany, and it is one of the largest university buildings in the city. The library's collections were rebuilt with donations from all around the world, outraged by the barbaric act which it had suffered. In 1940, during the second German invasion of Leuven, the building largely burnt down, with the loss of 900,000 manuscripts and books. The building was rebuilt after the war in accordance with Warren's design.
The library's tower included a 48-bell Gillett and Johnston carillon installed in 1928, and dedicated to the memory of the engineers of the United States who died in all wars. After having fallen into complete disrepair and neglect, efforts began in the early 1980s to restore the carillon. With the cooperation of the Belgian American Educational Foundation and the University, organized efforts to restore the carillon began. The restoration fell to Eijsbouts and the bell count increased to 63. The newly restored carillon was rededicated in October 1983, with a series of lectures, concerts, statements from diplomats including Ronald Reagan, and European carillon keyboard standardization agreements.
The library's collections were again restored after the war, and by the time of the split in 1968 had approximately four million books. The separation of the university into distinct French-language and Dutch-language institutions in 1968 entailed a division of the central library holdings. This was done on the basis of alternate shelfmarks (except in cases where a work clearly belonged to one section or the other, e.g. was written by a member of faculty or bequeathed by an alumnus whose linguistic allegiance was clear). This gave rise to the factoid that encyclopedias and runs of periodicals were divided by volume between the two universities, but actually such series bear single shelfmarks.
The building on the Mgr. Ladeuzeplein is now the central library of the Katholieke Universiteit Leuven.
