Ahmet declares himself as the sultan of Anatolia afterhearing about Selim's defeat by their father, and begins fighting against one of his nephews (whose father had already been killed).

He captures Konya, and although his father Bayazid asks him to return to his sanjak, he insists on ruling in Konya.

He also attempts to capture the capital; but he fails because the soldiers block his way, declaring their preference for a more able sultan.
