Murad II left the throne after the treaty of Segedin and went to Manisa. 12 years old heir apperant Mehmed ascended to the throne. However, the state had confused. Moreover, in Europe a new Crusade had organised against this nearly infant sultan. Mehmed II wrote a letter to Sultan Murad II and invited him to the throne.

Mehmed’s famous letter:

If you are the sultan, you have to lead your country in this unfortunate situation. Please, come in front of your army. If I am the sultan, I remind you to obey my commands and I command: Come in front of your army.
