Shams al-Dīn Meḥmed I Beg (Turkish: Şemseddin Mehmed Bey; died 20 June 1277 or 30 May 1279) was Beg of the Ḳarāmān from 1263 until his death. Ḳarāmān was a Turkish principality in Anatolia in the 13th century. His father was Karaman Bey.
Meḥmed and his brothers joined Hatīroghlu Sharaf al-Dīn's revolt against the Mongols. Sharaf al-Dīn granted Meḥmed the lands his father Ḳarāmān formerly ruled over and dismissed Badr al-Dīn Ibrāhīm from that position. Meḥmed further expanded his territory towards the Mediterranean coast and eliminated the Mongol force of 200 men in Ulukışla. When Sharaf al-Dīn was killed by the Mongols in 1276, Badr al-Dīn attempted to take revenge on Meḥmed but was defeated by him in Göksu Valley.[1]
Next year he allied himself with Baybars of Mamluks. In May he captured Konya, the Seljuk capital. But instead of declaring himself as the sultan he supported his puppet Jimri as sultan, and in turn Jimri appointed him as vizier of the Seljuks on 12 May 1277.[2] As vizier Mehmet issued his famous firman (decree) ordering the Turkish language to be used instead of Persian and Arabic in government offices. But his service term in Konya lasted only about a month. Hearing news of the approaching Mongol army, both Mehmet and Jimri fled from Konya.[3] But the Mongols chased him, and during a clash in Mut Mehmet and his two sons were executed in August 1277.[4]
He was succeeded by his brother Güneri.
