The history of higher education in this area dates back to almost three centuries ago, i.e. 1707, when the first institution of higher education was founded in Osijek. It was the Higher Theological School, which was opened in the academic year 1707/1708 as the Studium Philosophicum Essekini, and included a three-year course of studies in philosophy.
The initiative for the founding of the University of Osijek started in 1975 and it is important to note that on 26 March 1975 the Croatian Parliament passed the Decision granting consent for the establishing of the University of Osijek. Two months later, on 31 May 1975, the Agreement concerning the founding of the University of Osijek was signed by the Faculty of Economics, the Faculty of Agriculture and Food Technology, the Institute of Agriculture, the Zagreb School of Engineering and Naval Architecture for Mechanical Engineering Studies in Slavonski Brod, the Teacher Training College in Osijek, the Zagreb Music Academy for the Music Department in Osijek, the City Library and the Historical Archives in Osijek.
This is why we celebrate 31 May as the day when the University of Osijek was founded.
