In the time of Timur Fujah was a fortress of Sarukhan, but had been previously in Genoese hands.
Though Yahsha Bey, grandson of Mahommed Karaman Oghlu, had declared himself the successor of the Seljukian sultans, the princes of Aidin, Sarukhan, Menteshe, Kermian, Hamid, Tekke and Karassi declined to recognize his authority, and considered themselves independent, each in his own dominions.
The principalities of Aidin, Menteshe, Sarukhan and Kermian were annexed to Bayezid's dominions to punish their rulers for having joined with the 'Karamanian prince in rebellion.
Prodigies of valour on the part of Bayezid's troops could not make up for the defection of the newly-absorbed levies from Aidin, Sarukhan and Menteshe who went over to their former princes in Timur's camp. The rout of the Turkish army was complete.
