Stefan Leder is Professor of Arabic and Islamic Studies at Martin-Luther-University in Halle/Germany and was the director of the Orient-Institut Beirut from October 2007 to September 2017, including the institute's Istanbul branch (Orient-Institut Istanbul) till 2010.
Prior to his engagement with the OIB, he was chairman of interdisciplinary research institutions funded by the DFG (German Research Foundation) and by his home university. His research topics combine history, literature & textuality, applying text criticism, discourse analysis and intertextual analysis. His published work covers Arabic historiography, with particular attention given to narrativity; Islamic Tradition under the perspectives of authority of knowledge, transmission and moral politics; and the Bedouin patrimony in Arabic thought and discourse. He also writes on the history of Oriental Studies in Europe. His current research projects concern medieval political literature, and the intellectual and political role of the Ayyubid chancery exemplified by the critical edition of al-Qadi al-Fadil’s correspondence.
Political thought in the Middle East, nourished by the traditions of Antiquity and of Asiatic, mainly Iranian, Indian and of Arabic origins, elaborated a variety of conceptual frameworks. Political philosophy, teachings of wisdom, ethics, Islamic law and examples from history play an important part, but authors also discuss particular political matters.
As head of Saladin's chancellery, al-Qāḍī al-Fāḍil (1135-1200) designed and carried out diplomatic correspondence, engaged in the organization of state finances and politics, and entertained an extensive literary communication with most of the conspicuous intellectuals of his time.
