Kerîmeddin Karaman Beg (Turkish) (Arabic: كريم ٱلدين Karīm al-Dīn Karaman Bey) was a Turkmen chief founder of the dynasty Karaman-oğhlu or Karamanoğulları. The province and city of Larandia was renamed Karaman in his honor.
He was the son of Nûre Sûfî Bey, a Turkmen leader from Arran, who established himself in the Taurus Mountains near Larandia and who became a Seljuk vassal. Some time before 1256, Karaman Bey officially succeeded his father (who had already left him the effective power several years prior in order to pursue a life in seclusion). In about 1260 Karaman makes his first appearance in the Isaurian-Cilician Taurus regions.
Although the points of detail can probably never be determined, it can be accepted that Karaman started life as a woodcutter and timber merchant who brought supplies from the western Taurus to the little town of Laranda. 
In the struggle between Izz al-Din Kaykaus (1246-1260) and his rival Kilidj Rukn al-Din Arslan IV Karaman supported the first. But Kilidj Rukn al-Din Arslan with the help of Parvaneh (Parvana) Sulayman Muin al-Din who was the one who had the real power, and the Mongols, managed to eliminate most of the hostile emirs or begs, but could not capture or kill Karaman and thus, tried to appease him by granting him Larandia and Ermenek and by giving his brother Buñsuz the position of amir djandar in Konya. The fall of Izz al-Din is said to have been one of the causes and possibly was the occasion of or pretext for his uprising. Izz al-Din was regarded, relatively speaking, as an ally of the Turcomans against the Mongols, and the efforts of Rukn al-Din to win the support of the Karamanids were in vain.
Karaman Bey expanded his territories by capturing castles in Ermenek, Mut, Ereğli, Gülnar, Mer and Silifke. The year of the conquests as indicated in the Encyclopedia of Islam (vol. IV, page 643) is 1225, during the reign of Ala al-Din Kaykubadh I (1220-1237), which seems excessively early. Karaman Bey's conquests were mainly at the expense of the Kingdom of Lesser Armenia (and perhaps at the expense of Rukn al-Din Kilidj Arslan IV, 1248-1265). He fought against the Armenians on the Isaurian-Cilician borders to such extent that King Hethum I (1226-1269) had to place himself voluntarily under the sovereignty of the great Khan, in order to protect his kingdom from Mamluks and Seljuks (1244). King Hethum I had to intervene several times, and succeeded in repulsing Karaman.
Good relations between the Seljuqs and the Karamanids did not last. In 1261, on the pretext of supporting Kaykaus II who had fled to Constantinople as a result of the intrigues of the chancellor Pervâne, Karaman Bey and his two brothers, Zeynül-Hac and Bunsuz, marched toward Konya, the capital of Seljuqs, with 20,000 men. A combined Seljuq and Mongol army, led by the chancellor Mu'in al-Din Suleyman, the Pervane, defeated the Karamanid army and captured Karaman Bey's two brothers.
According to the Armenian chroniclers, in one of the battles against king Hethum at the fort Meniaum (probably Mennan near Ermenek) his brother Buñsuz and his brother-in-law were killed (information which is in contradiction to other sources that say that Buñluz who was amir djandar in Konya was jailed after the death of Karaman), and he himself was wounded and died shortly after, about 1262. Also, some of his children and members of his family were taken prisoners and held in the Gevele fortress near Konya . The central authority was to some extent re-established, at least in Ermenek, where, until 1276, an official Seljukid governor held office without any recorded difficulties.
Karaman is supposedly buried in Nalkasun near Ermenek, but according to the inscription on the tomb, it belongs to his son Mehmed. His children were freed by Pervane Muin al-Din Sulaymab upon Sultan Kilidj Arslan IV's death in 1265, except his second son, Ali Beg who remained as hostage in Kayseri. Mehmed will regain power in 1276 in Ermenek.
