Sultan Bayezid I launched several campaigns into Anatolia in response to the anti-Ottoman activities of the Anatolian principalities. As a result of these campaigns, Sultan Bayezid I brought the Anatolian principalities under Ottoman rule. Following the subsequent Ottoman - Timurid conflict, the Ottoman Empire entered a period of interregnum, and the rulers of the Anatolian principalities re-established their dominance in their former territories.
