Keykubad Bey

Keykubad Bey was the second ruler of the Kubadids, a Turkmen principality on Anatolia's Black Sea coast, succeeding his father Tâceddin Altunbaş around 1357. He kept Ladik as his capital in the lands around Ladik and Kavak, while his tutor Emir Taşan broke away to found the neighboring Taşanoğulları beylik.

Under Keykubad the Kubadids became vassals of the Amasya rulers Hacı Şadgeldi and Emir Ahmed. His son Ali Bey campaigned against the neighboring Taceddinoğulları and won Samsun, then succeeded him.
