Abstract
During his reign, Murad II made important conquests in Anatolia and Rumelia and expanded the borders of his state. However, after the unsuccessful siege of Belgrade, a series of failures in Rumelia led to the Battle of Zlatitsa. During the Battle of Zlatitsa, the Karamanids, who were in alliance with the Crusaders led by Hungary also acted against the Ottomans in Anatolia. Eliminating the Crusader threat in Rumelia, Murad II advanced on the Karamanids and took also the control in there. After the adventurous and difficult reign, Murad II concluded that the state got out of the difficult situation by making the Peace of Szeged with Hungary and the Yenisehir Sevgendnâme with the Karamanids, he abdicated the throne in favor of Mehmed II.
Murad II settled in Manisa after he withdrew from the state affairs. As a result of the change in the Ottoman throne, the rivals of the Ottoman Empire came together and formed a new Crusader army in Rumelia under the leadership of Hungary and attacked the Ottoman Empire. In order to get rid of this difficult situation, the state dignitary, who was with Murad II's reign and continued their duty during the reign of Mehmed II had planned to bring back Murad II, who was in Manisa. But the other statemen who were followers of Mehmed II wanted the young sultan to be the head of the army in this critical period and consolidate his reign. In the end, as a result of the activities of the faction that wanted Murad II to be at the head of the army and headed Grand Vizier Candarlı Halil Pasha, Murad II took over the state again and managed to stop the Crusaders in the Battle of Varna. During this transition, the letter sent to persuade Murad II with the purpose of encounter the Crusaders passing in the letters “Father, if you are the sultan, come and lead your armies. If I am the sultan I hereby order you to come and lead my armies.". These words were firstly found in the sixth register of Ibn Kemal's work named "Tevârîh-i Âl-î‘ Osmân "in historical sources.
This work had revealed the letter incident as it became the source of the following works. However, in response to this narrative, we could not find such information in the Anonymous Gazavâtnâme, which witnessed the War of Varna, and other chronicles written in this period. For this reason, the narration in Ibn Kemal’s work has been analyzed considering the political and social needs of the period in which the work was written.
