History
Sinop was an important Black Sea port during the Middle Ages. It was captured by Kaykaus I of Seljuks in 1214. The mosque was commissioned by his brother Alaattin Keykubat I in the 1220s. The trustee of the mosque building was Atabeg Esedüddin Ayas, the former Artuqid (an Anatolian beylik) bey, who escaped from his beylik after a coup d'état and took refuge with the Seljuks. But after Manuel I of Trebizond captured Sinop, most of the mosque was demolished. Turkish control was restored in 1264 and Seljuks vizier Pervâne rebuilt the mosque in 1267. The city fell under the rule of the Candar dynasty and during the 1340s İbrahim of Candar built a tomb in the northeast corner of the mosque's courtyard.
