İshak of Karaman

İshak of Karaman was a bey of Karaman Beylik, a Turkish principality in Anatolia in the 15th century. He succeeded his father İbrahim Bey in 1464. He was the legal heir to throne. But his mother was a concubine and his half brothers opposed him.^[1] At the time of his father's death, he was a local governor in Silifke. When he tried to march to his capital Konya, he learned that his younger brother Pir Ahmet had put a claim on the throne. This resulted in an interregnum in the beylik. The help of Uzun Hasan, the sultan of Akkoyunlu (White Sheep) Turkmens enabled him to ascend to the throne, albeit for a short reign. Because, Pir Ahmet appealed to Ottoman sultan Mehmet II for help. He offered Mehmet some territory which İshak refused to cede. With Ottoman help, Pir Ahmet defeated İshak in the battle of Dağpazarı. İshak had to be concerned with Silifke for an unknown time.^[2]
