Archivum Ottomanicum concerns itself primarily with Ottoman history and Ottoman philology. However, the editors also welcome articles on subjects related to Ottoman studies in the history and culture of Europe, including Danubian Europe, the Black Sea area and the Caucasus, and in the history and culture of the Arab and the Iranian lands as well as Byzantium. The publication of historical documents and records and their interpretation are of special interest.
