The period of fetret

After the Ankara Battle, the Turkish unity in Anatolia was desolved and the Ottoman Empire faced with the danger of destruction. The sons of Bayezid I had began a throne struggle after his death. Thus, the most chaotic interragnum had began in the Ottoman history. Because of the Byzantine intrigues and Timur’s destruction the civil war had begun among the shehzades. Suleyman Celebi in Edirne, Isa Celebi in Bursa, Mehmed Celebi in Amasya, and Musa in Balikesir declared their own sultanates.

Mehmed and Musa made an allience, and killed Isa. Mehmed knew that Suleyman must have been killed too. For this purpose, he sent Musa against Suleyman to Edirne. Musa had defeated his brother Suleyman and invaded Edirne, but did not keep his promise and declared himself as the sultan of Edirne. In 1413, Mehmed defeated Musa and he ended the interregnum.

After Mehmed had restored the unity in Anatolia and Roumelia, he struggled with two revolts. One was the revolt of Seyh Bedrettin, the other was the revolt of Duzmece Mustafa. Seyh Bedrettin was born in Simavna near Edirne and he was educated in the important scientific and cultural centres as Bursa, Konya, and Cairo.

Seyh Bedrettin and his friends Torlak Kemal and Borkluce Mustafa designed a tarikat (sect) in Iznik and they have began to provoke people with extremist islamic ideas. After a while, Seyh Bedrettin and his friends came to Deliosman and started a riot. In Izmir Borkluce Mustafa and in Manisa Torlak Kemal joined to the revolt. Mehmed sent his forces to Izmir and Manisa and repressed the revolt. Seyh Bedrettin was caught and after he judged by Kadi (Judge) of Serez, he was sentenced to death.
