Katholieke Universiteit Leuven

In 2021–22, more than 65,000 students were enrolled, with 21% being international students. Its primary language of instruction is Dutch, although several programs are taught in English, particularly graduate and postgraduate degrees. KU Leuven previously only accepted baptized Catholics, but is now open to students from different faiths or life-stances. While nowadays only the acronymic name KU Leuven is used, the university's legal name is Katholieke Universiteit Leuven, officially Katholieke Universiteit te Leuven, which translates in English as Catholic University at Leuven. However, the acronymic name is not translated in official communications, like its similarly named French-language sister university Université catholique de Louvain (UCLouvain).

Recorded constituent parts are Institute of Philosophy, KU Leuven, KU Leuven Publication, University Hall and KU Leuven Libraries. It is associated with Belgium. The record gives 1970 as its date of establishment or first appearance. It forms part of ELIXIR Belgium. Its recorded seat is Leuven.

The town of Leuven has been the seat of four universities, with the first one established in 1425. Since then, the organisation has been abolished and refounded multiple times.

The Old University of Leuven (or Studium Generale Lovaniense) was founded in 1425 by Duke John IV of Brabant, the civil authorities of Brabant, as well as the municipal administration of the city of Leuven, despite the initial opposition of the chapter of Sint-Pieter. For centuries, the university flourished due to the presence of famous scholars and professors, such as Adriaan Florenszoon Boeyens (Pope Adrian VI), Desiderius Erasmus, Johannes Molanus, Juan Luís Vives, Andreas Vesalius and Gerardus Mercator. After the French Revolution, the university was formally integrated into the French Republic when the Holy Roman Emperor, Francis I, ceded then Austrian Netherlands to France by the Treaty of Campo Formio signed on 17 October 1797. A law dating to 1793, which mandated that all universities in France be closed, came into effect. The old University of Leuven was abolished by decree of the Département of the Dyle on October 25, 1797.

A few years after French rule came to an end, when Belgium was part of the United Kingdom of the Netherlands, king William I of the Netherlands in 1817 founded a secular university in Leuven, the State University of Leuven, where many professors of the Old University of Leuven taught. This university was abolished in 1835.

• Illustration — Arenberg Castle, purchased by the Catholic University of Leuven in 1921 The Catholic University of Leuven was founded in 1834 in Mechelen by the bishops of Belgium, after an official Papal Brief of Pope Gregory XVI. This new Catholic university stayed only briefly in Mechelen, as the bishops already moved the university headquarters to Leuven on 1 December 1835, where it took the name Catholic University of Leuven. This occurred after the closure of the State University of Leuven in 1835, where many professors of the Old University of Leuven had taught. KU Leuven is generally (but controversially) identified as a continuation of the older institution; controversy lays in the fact that this link to the Old University cannot be maintained from a purely juridical perspective as the Old University was suppressed under French rule. In its statutes, KU Leuven officially declares against the rulings of the Court of Cassation and the Cour d'Appel, to be the continuation of the Studium Generale Lovaniense established in 1425, and together with UCLouvain it sets out to celebrate its 600th anniversary in 2025. The original establishment during medieval times and subsequent re-foundation at a later period represents a fate shared by the University of Leuven (KU Leuven) with several other well-known European universities that experienced the upheavals of revolutionary times. In 1920, the Catholic University of Leuven for the first time admitted female students, lagging some 40 years behind the Belgian universities of Brussels, Liège and Ghent.

In 1968, tensions between the Dutch-speaking and French-speaking communities led to the splitting of the bilingual Catholic University of Leuven into two "sister" universities, with the Dutch-language university becoming a fully functioning independent institution in Leuven in 1970, and the Université catholique de Louvain departing to a newly built greenfield campus site in the French-speaking part of Belgium. KU Leuven's first rector after the split was Pieter De Somer. In 1972, the university set up a separate entity, Leuven Research & Development (LRD), to support industrial and commercial applications of university research. It has led to numerous spin-offs, such as the technology company Metris, and manages tens of millions of euros in investments and venture capital. The university's electronic learning environment, TOLEDO, which started in September 2001, was gradually developed into the central electronic learning environment at the KUL. The word is an acronym for TOetsen en LEren Doeltreffend Ondersteunen (English: "effectively supporting testing and learning"). It is the collective name for a number of commercial software programs and tools, such as Blackboard. The project offers the Question Mark Perception assignment software to all institution members and has implemented the Ariadne KPS to reuse digital learning objects inside the Blackboard environment. On 11 July 2002, the KU Leuven became the dominant institution in the "KU Leuven Association" (see below). KU Leuven is a member of the Coimbra Group (a network of leading European universities) as well as of the LERU Group (League of European Research Universities). Since November 2014, KU Leuven's Faculty of Economics and Business is accredited by European Quality Improvement System, which is a leading accreditation system specializing in higher education institutions of management and business administration. As of academic year of 2012–2013, the university held Erasmus contracts with 434 European establishments. It also had 22 central bilateral agreements in 8 countries: the United States, China, South Africa, Japan, the Democratic Republic of Congo, Vietnam, Poland, and the Netherlands. The vast majority of international EU students came from the Netherlands, while most non-EU ones come from China. Even though the university is financially independent from the Catholic Church, representatives from the Catholic Archdiocese of Mechelen–Brussels sit on the Board of Trustees, and are yielded chairmanship powers and veto powers in certain decisions. In December 2011, the university changed its official name to KU Leuven in all official communications and branding. While its legal name remains to be Katholieke Universiteit Leuven, the university uses its short name or acronym, KU Leuven, in all communications, including academic research publications. The long name is only used in legally binding documents such as contracts and only on the first instance, according to university's communication guidelines. According to its then rector, the change is intended as a way to emphasize its history of freedom of academic inquiry and its independence from the Church, without erasure of its Catholic heritage. Since August 2017, the university has been led by Luc Sels who replaced former rector Rik Torfs. The Belgian archbishop, Luc Terlinden is the current Grand Chancellor and a member of the university board. KU Leuven hosts the world's largest banana genebank, the Bioversity International Musa Germplasm Transit Centre, that celebrated its 30th anniversary in 2017 and was visited by Deputy Prime Minister and Minister for Development Cooperation, Alexander De Croo. In 2018, a student of African origin, Sanda Dia, died during a cruel hazing ritual to enter the Reuzegom fraternity. The perpetrators, whose parents mostly belong to the upper class, are being prosecuted, but were so far only lightly sanctioned by the university authorities. As a consequence of these events, which attracted international media coverage, the institution received criticism as to how it handled the matter. In 2023, 18 students were fined 400 Euros and community service for their involvement in the death and the degrading treatment. Historically, the Catholic University of Leuven has been a major contributor to the development of Catholic theology. The university is dedicated to Mary, the mother of Jesus, under her traditional attribute as "Seat of Wisdom", and organizes an annual celebration on 2 February in her honour. On that day, the university also awards its honorary doctorates. The neo-Gothic seal created in 1909 and used by the university shows the medieval statue Our Lady of Leuven in a vesica piscis shape. The version used by KU Leuven dates from the 1990s and features the date 1425 in Times New Roman.

Academics at KU Leuven is organized into three groups, each with its own faculties, departments, and schools offering programs up to doctoral level. While most courses are taught in Dutch, many are offered in English, particularly the graduate programs. Notable divisions of the university include the Institute of Philosophy and the Rega Institute for Medical Research. The students of the university are gathered together in the student council Studentenraad KU Leuven.

The following libraries are found at its Leuven campus: • 2Bergen — Biomedical Library • 2Bergen — Campuslibrary Arenberg (exact sciences, engineering sciences, industrial engineering sciences, bio-engineering sciences, architecture and kinesiology and rehabilitation sciences) • Artes — Ladeuze & Erasmushuis (Humanities & Social Sciences Group and the Faculty of Arts) • Library of Psychology and Educational Sciences • Law Library • Library of Social Sciences • Library of the Institute of Philosophy • AGORA Learning Centre • EBIB Learning Centre • MATRIX (music and audio recordings library) • Maurits Sabbe Library (Library of the Faculty of Theology and Religious Studies)

Universitair ziekenhuis Leuven (UZ Leuven) is the teaching hospital associated with the KU Leuven. Its most well known and largest campus is Gasthuisberg, which also houses the faculty of pharmaceutical sciences and most of the faculty of medicine.

KU Leuven scientists have managed to produce a solar hydrogen panel, which is able to directly convert no less than 15 per cent of sunlight into hydrogen gas, which according to them is a world record. In the solar hydrogen panel the hydrogen and oxygen evolution reactions are performed in the gas phase in cathode and anode compartments separated by a membrane. Anion exchange membranes provide an alkaline environment enabling the use of earth abundant materials as electrocatalysts. According to IEEE Spectrum in 2019 this is a giant leap from 0.1% efficiency 10 years earlier. This technology bypasses the conversion losses of the classical solar–hydrogen energy cycle where solar power is first harvested via a solar panel and only then to converted to hydrogen with electrolysis plants.

KU Leuven publishes Jura Falconis, a student-edited law review of the Faculty of Law. It was founded by a group of students from the Law Faculty of the Katholieke Universiteit Leuven who, in 1964, conceived the idea of producing their own law journal grafted on the famous American law reviews. Every year, Jura Falconis organizes the Jura Falconis Prijs, an award for the best legal dissertation. Students at Flemish faculties of law submit their dissertations, which are judged by a panel of professors of law, including a judge of the Belgian Court of Cassation.
