The political unity established by Yıldırım Beyazıt ended after the Battle of Ankara (1402). In the period of Çelebi Sultan Mehmet who was under cover of Timur, Çorum was administered by Ottoman Empire. This period lasted until the republic period. Çelebi Sultan Mehmet founded a commandership in Çorum and he had Köpökoğlu Sülü and his brother Hüseyin killed. He also had to cope with Babaiye Religious Group supporters.
Çelebi Mehmet who united Ottomans assigned his son Murat II as the governor of Amasya. Murat’s assistant Hamza Bey served Çorum a lot. Çorum changed into a city where Karayazıcı rioted.
