Kurdoğlu Bey

Kurdoğlu Bey was the blood brother of Süleyman Şah and leader of many nomad families of the Kayı tribe. He took a dark turn after his wife and children were martyred by Mongols, bearing a deep hatred for his blood brother due to his waging of wars. He secretly plots with the Templars to make himself the Bey of the Kayı tribe, and initially succeeds by force, but fails to kill Ertuğrul and Süleyman Şah and is thus overthrown and beheaded by Ertuğrul.
