Catholic University of Leuven

The Catholic University of Leuven (1834–1968) was a private Roman Catholic institution of higher learning founded by the Belgian Catholic episcopate shortly after Belgium's independence in 1830. Initially established as the Catholic University of Belgium in Mechelen in November 1834, it moved to Leuven in December 1835, adopting its historic name to claim continuity with the Old University of Leuven (founded 1425). Although officially a new entity, it was widely regarded by its founders as the restoration of the medieval university, a claim that faced legal and political challenges from liberal factions. The institution operated as a bilingual university until 1968, when linguistic tensions led to its division into the Dutch-speaking KU Leuven and the French-speaking Université catholique de Louvain.

The university was founded on November 8, 1834, in Mechelen based on authorization from a Papal Brief by Pope Gregory XVI. The first rector was the priest and historian Pierre-Théodore Verhaegen. The move to Leuven on December 1, 1835, was intended to leverage the prestige of the former university but outraged Belgian liberal opinion, which viewed it as an attempt to usurp the past of the secular state university. The institution celebrated its silver jubilee in 1859 and its 50th anniversary in 1884. In 1962, the French and Dutch sections became autonomous within a common structure, a precursor to the final split in June 1968 which resolved the linguistic dispute by creating two independent sister universities.
