The Orient-Institut Beirut (OIB) is an academic research institute focusing on the Arab region and the wider Middle East. The OIB was established in Lebanon on the initiative of the German Oriental Society in 1961, and has been part of the Max Weber Foundation – German Humanities Institutes Abroad since 2003. It is funded by the German Federal Ministry of Education and Research. Since 2009, the OIB also has an office in Cairo.
The OIB conducts and supports research in the humanities and social sciences. The systematic study of primary sources and cooperation with regional actors and institutions provides a common conceptual framework. Research projects at the OIB are currently located in and between the academic disciplines of Arabic and Islamic studies, history, political science and media studies, and deal with questions related to history, literature, geography and the social sciences. The institute also supports projects in the fields of religious studies, history of art and social anthropology.
The OIB publishes three series, Bibliotheca Islamica (BI), Beiruter Texte und Studien (BTS), and Orient-Institut Studies (OIS). BI is dedicated to the critical edition of mostly Arabic manuscripts, while BTS and the online series OIS are dedicated to the study of the history, society, politics and literature of the region.
