1. Historical Overview

The University of Osijek traces its academic lineage to 1707 with the founding of the Studium Philosophicum Essekini by the Franciscans. Over time, it evolved through the addition of theological, pedagogical, and economic faculties, culminating in its formal establishment in 1975. The university was renamed in 1990 after Josip Juraj Strossmayer, a prominent Croatian bishop and patron of education. Today, it is the third oldest and fourth largest university in Croatia, with its administrative center housed in the historic Tvrđa Fortress—a site of immense architectural and cultural value (EFOS History).
