Ibrahim I of Karaman

Bedreddin İbrahim was a son of the Karamanid ruler Mahmut Bey. After his elder brother Musa succeeded in 1312, İbrahim claimed the throne and rose in revolt in 1318, winning it with the backing of the Egyptian Mamluks; Ibn Battuta once served as his envoy to Cairo.

Between 1332 and 1340 he abdicated in favour of his brother Halil, but after Halil died in 1340 he resumed rule. He campaigned against the Armenian Kingdom of Cilicia and was certainly still alive in 1343.
