Analysis of information sources in references of the Wikipedia article "Suleiman the Magnificent" in English language version.
That the Ottomans might have had a different view was demonstrated by Sultan Sulaymān the Magnificent, who called himself the shah of Baghdad in 'Iraq (Shah-i Bagdād-i 'Irāq), the Caesar of Rome (qayṣar-i Rūm), and the sultan in Egypt (Miṣra (i.e. Mısıra) Sulṭān) in the inscription in the fortress of Bender (Bendery, Tighina) in Moldova, AH 945 (29 May 1538–18 May 1539). The title qayṣar-i Rūm (Caesar of Rome) was a traditional designation of the Byzantine emperor in Persian and Ottoman sources (from the Arabic al-qayṣar al-Rūm).
