The University of Zagreb (Croatian: Sveučilište u Zagrebu, Latin: Universitas Studiorum Zagrabiensis) is the biggest Croatian university and the oldest continuously operating university in the area covering Central Europe south of Vienna and all of Southeastern Europe. The beginnings of the later university date back to 23 September 1669 when Emperor and King Leopold I Habsburg issued a decree granting the establishment of the Jesuit Academy of the Royal Free City of Zagreb. According to that document the study of philosophy in Zagreb acquired a formal and legal status as Neoacademia Zagrabiensis and officially became a public institution of higher education. The academy was run by the Jesuits for more than a century until the order was dissolved by Pope Clement XIV in 1773. Under a new leadership in 1772 the academy enrolled a total of 200 students. In 1776 Empress and Queen Maria Theresa issued a decree founding the Royal Academy of Science (Latin: Regia Scientiarum Academia). It consisted of three studies or faculties of philosophy, theology, and law.
