Badr al-Din Mahmud Bey

Badr al-Din Mahmud Bey (c. 1250–1308), fourth Karamanid ruler, was a son of its founder Karaman Bey. In 1293 he drove Cypriot crusaders from Alanya, and in 1300 succeeded his brother Güneri at Laranda; he was the first Karamanid to style himself sultan.

He defeated an Ilkhanid army and, after Hethum II of Armenia died in 1307, raided Armenian Cilicia. In 1308 he won near Anamur but died of his wounds. His son Musa succeeded him.
