The city was established in 3 century BC. In ancient times it was known for its merchandise. At  2nd century BC it was a center of piracy: It was occupied by arab and byzantine people and since 11 century became the part of Cilician Armenia.  During the reign of Toros the Second, Korikos joined Clician Armenia. In 1206 Levon II completed the reconstruction of Korikos. In 1219, after the death of Levon II,  Vahram, the governor of Korikos, tried to capture the Armenian throne. The Hethumid Guardian executed him and handed Korikos to his brother Oshin.At about 1300’s Korikos was living a flourishing period but in  1320s, Egyptian mamluks were regularly attacking. Until the 17th century, Korikos remained the Armenian bishopric center. However, under the influence of Turkish persecutions and violence, the number of armenian population gradually reduced.

The city had two strong fortresses, which had four big reservoirs, wells and a church with ornamented columns. On the walls of the central palace of the city were made different mentions with the names of Levon B and Hetum A kings. The historian Hetum was born and lived in Korikos.
