The Saint Joseph University of Beirut (USJ) founded the Oriental College in 1902, which later evolved into the Institute of Oriental Studies (ILO). The College aimed to educate students on the rich cultural heritage of the Arab East and to advance research in related disciplines. Aligned with the Arab literary revival, it emerged as a central force in shaping the region’s intellectual and cultural landscape.

Jesuit scholars, including Louis Cheikho and Henry Lammens, shaped generations of specialists in Arabic and Oriental literature, sociology, and Islamic studies. The College’s publications, notably the Saint Joseph University Journal, the Mashriq Journal, and other research works, championed rigorous scholarship and highlighted the depth and diversity of Eastern and Arabic culture.

After a suspension of activities during World War I, the College resumed activities in 1933, focusing on Oriental literature. Key figures of this period include the Jesuit fathers Motard and Mesbian, Professor Fouad Afram al-Bustani, and Prince Maurice Chehab.

In 1936, USJ formalized its programs under the Institute of Oriental Studies, with oversight from the Faculty of Arts at the University of Lyon, France. ILO attracted distinguished scholars, including Father Henry Fleish, an expert in Arabic linguistics, and Professor Khalil Jarr, a specialist in Arabic philosophy. In 1977, USJ formally established the Faculty of Humanities, integrating ILO, ensuring its continued growth and influence.

Since 2002-2003, ILO has adopted the European Credit Transfer and Accumulation System (ECTS) enhancing academic standards, fostering global collaboration, and reinforcing its distinctive focus on Arabic and Islamic studies while strengthening ties with the Arab and Islamic worlds.
