Tamerlane defeated Ottoman Sultan Yıldırım Beyazıt in 1402 in the savanna of Çubuk, Ankara. And after put all the territories of Ottoman Empire under his domination. He gave back their territories to Turkmen Beyliks like Karamanoglu, Germiyanoglu and Aydınoglu which were terminated by Ottomans and helped them to recreate their beyliks. Tamerlane made an expedition to dispense negative reactions as he had defeated Ottoman Sultan Beyazıd who was known as Conqueror and Veteran and put the ottoman in a difficult position. This place was İzmir which was the only territory under the control of non-Muslims in Anatolia and was controlled by Rhodes nights. In the same time İzmir was only city surrounded and wasn’t conquered by Beyazıt. Tamerlane conquered the city and banished the nights (December 1402- January 1403). Tamerlane who took over the city from the Christian nights tried to restitute his negative image as he made a war against a state who is veteran and also a Muslim.
