. The University of Nagyszombat, established in 1635, is Hungary's first, continously operating university. It's successors are the Eötvös Loránd University of Budapest and the Pázmány Péter Catholic University. A significant part of the university's archival resources were destroyed in a fire at the Hungarian National Archives during the Hungarian Revolution of 1956. Therefore it is extremely difficult to  compile a list of the students who studied at the first Hungarian university. Recently, in Esztergom, new, previously unknown sources emerged about the students of the university. In this article we summarise the findings that can be drawn from the new documents regarding the students that studied at the Faculty of Arts and Theology of the University. The article analyses the university's geographical area, the evolution of the number of students and the social stratification of the student population and nationality, the proportion of foreign and national students.
