Çankırı, located in the northernmost part of Central Anatolia, remained under the domination of the Hittites, Paphlagonians, Persians, Galatians and Romans throughout the historical process. Çankırı, which could not be conquered despite the raids organized by the Umayyads and hosted many civilizations, was conquered by Karatekin Bey, one of the commanders of Süleyman Shah, in 1074. Emir Karatekin is an important figure in Turkish-Islamic history as he was the first Muslim Turkish commander to conquer the Western Black Sea region. As a result of Emir Karatekin's military activities in this region between 1074 and 1084, Çankırı, Kastamonu and Sinop regions were conquered by the Turks and went down in history as the "Conqueror of Çankırı". Until his death, he was the sole administrator of Çankırı, Kastamonu and Sinop regions, with Çankırı as the center. Karatekin, who established a principality affiliated with the Anatolian Seljuks in the regions he conquered, ruled this principality until his death. After his death, Emir Karatekin was buried in his grave in Çankırı Castle.
