Established in 1919, the University of Ljubljana is the first and the largest university in Slovenia. With a current enrolment of 56,000 students, it ranks among the biggest universities in the world. The university currently has 22 faculties, one college and three academies, scattered around urban Ljubljana.

The University of Ljubljana was established in 1919 on the foundations of a long- established pedagogical tradition. For almost half a century it remained the only Slovene university, until 1975 when it was joined in 1975 by the University of Maribor. Since that time two other universities have been established - the University of Primorska in 2003 and the University of Nova Gorica in 2006. Nearly one tenth of the inhabitants of the capital city of Ljubljana are students. The University of Ljubljana ranks among the largest universities in the world: it comprises a total of 20 faculties, three art academies and three university colleges, which employ some 1,700 full-time university teaching staff, assisted by nearly 600 technical and administrative staff. 56,000 undergraduate and postgraduate students participate in more than 130 undergraduate and 110 postgraduate programmes, mostly qualitative study programmes in both the humanities and scientific and technological fields, as well as in medicine, dentistry and veterinary science. The study courses and projects run at the University of Ljubljana follow the latest world discoveries and trends in the fields of art, science and technology, on both a domestic and an international level. The University of Ljubljana is a member of many international networks, including the Heads of University Management and Administration Network in Europe (HUMANE), the Inter-University Centre Dubrovnik, the Institutional Network of Universities from European Capitals (UNICA), Dean Conference - Alps-Adriatic, the European University Association (EUA), the International Association of Universities (IAU), the European Association for International Education (EAIE), the Utrecht Network and the Network of South East European Universities (AIMOS).
