Çankırı is the center of the province of the same name located in the Central Anatolia Region of Türkiye. The name of Çankırı was written as "Çangırı" or "Çengiri" by some Western travelers. The city was founded on the site of the old city called Gangra. It was previously affiliated with Paphlagonia. Then it was connected to the Pontus state and then to Galatia. Deiotarus, ruler of Galatia, made Gangra his center. The region, which was annexed to the Roman Empire in 25 BC, was a place of exile during the Byzantine period. The city of Germanikopolis mentioned in some sources is thought to be Gangra. Although the Islamic armies attacked several times during the Umayyad period, they could not capture this castle.

Çankırı and its surroundings were captured by Danışmendoğulları after the Malazgirt victory in 1071. The Crusader Army under the command of Raymond de Toulouse, who set out from Istanbul in 1101 to rescue Bohemond, the ruler of Antakya, who was captured by the Seljuks in Malatya and imprisoned in Niksar Castle, headed towards Çankırı after taking Ankara, but they could not enter the castle. The Crusader Army, which faced the Seljuk army near Amasya, was defeated. Although Byzantine Emperor Ioannes Komnenos was able to capture the castle after fierce battles in 1134, the Danishmends took the city back after he returned. Later, the Seljuks dominated the region. During the reign of Murad I, Çankırı and its surroundings were annexed to the Ottoman lands. Although Timur gave Çankırı to its former owners in 1402, Mehmet I took it back in 1439. Çankırı, which was the administrative center of a Livan province of Anatolia during the Ottoman period, was the center of a sanjak of the Kastamonu province before the declaration of the Republic. During the War of Independence, Çankırı played the role of an important intermediary center in the transportation of materials and people from Istanbul to Ankara via İnebolu. It became a provincial center during the Republic period. Source Wikipedia
