In 1919, the university comprised five faculties: law, philosophy, technology, theology and medicine.
The seat of the university was in the central Congress Square of Ljubljana in a building that had served as the State Mansion of Carniola from 1902 to 1918.
The building was first designed in 1902 by Jan Vladimír Hráský, and was later remodelled by a Czech architect from Vienna, Josip Hudetz.

In the mid-1920s, the university was renamed the "King Alexander University in Ljubljana" (Universitas Alexandrina Labacensis) and continued to grow despite financial troubles and constant pressure from Yugoslav governments’ centralist policies.
In 1941, Jože Plečnik's National and University Library was completed, as one of the major infrastructure projects of the university in the interwar period.

After the invasion of Yugoslavia in April 1941, the university continued to function under the Italian and Nazi German occupation, despite numerous problems and interference in its autonomous operation.
Several professors were arrested or deported to Nazi concentration camps and large numbers of students joined either the Liberation Front of the Slovenian People or the Slovenian Home Guard.
