The Battle of Frenkyazısı occurred in late 1386 or early 1387, between an Ottoman army under Murad I and a Karamanid force under Alaeddin Ali Bey. The engagement took place outside of Konya and resulted in a decisive Ottoman victory. In the aftermath the Karamanids had to accept Murad I's suzerainty and Ottoman supremacy over the western part of Anatolia was secured for the time being.
