According to the contemporary Muslim chronicler Ibn Bibi, the battle took place in 598 AH (October 1, 1201 – September 19, 1202).

Background
At the end of the 12th century, the Sultanate of Rum plunged into chaos due to Turkmen raids, Crusades and fierce power struggles among the descendants of Kilij Arslan II (1156–1192). In 1197, Rukn ad-Din Suleiman Shah, the fifth son of Kilij Arslan II, captured Konya and forced his brother Kaykhusraw I to leave the country and go into exile in Constantinople. Rukn ad-Din began a policy of expansion, challenging Byzantium, Armenian Kingdom of Cilicia and Kingdom of Georgia, uniting much of Anatolia under his rule.
The rise of the Georgian kingdom under King David IV the Builder continued under the reign of Queen Tamar, who managed to defeat a large Muslim coalition at the Battle of Shamkor in 1195.
Alarmed by Georgia's success, Sultan Rukn ad-Din Suleiman Shah, gathered the Muslim Anatolian beyliks against Georgia. The interests of Georgia and the Sultanate of Rum clashed on the southern coast of the Black Sea, where both sought to take advantage of Byzantine weakness and establish their own footholds.
Sultan Rukn ad-Din prepared for war to weaken the power of Christian Georgia and to conquer it. Between 1201 and 1203, Rukn ad-Din with detachments under the command of his brother, Mughis ad-din Tughril Shah of Elbistan, Mengujekid Bahram Shah of Erzincan, possibly with the help, of the Harput Artuqids as well as local Turkmen warriors, captured Erzurum and replaced the vassal of Georgia, Saltuk, with his brother Mughisuddin Togrul Shah.
Rukn ad-Din's messenger delivered letters to Tamar, demanding surrender and threatening extermination of disobedient Christians. Stating that "every woman is simple-minded...you...simple-minded queen...murderer and tax collector of Muslims." Tamar's first response was polite: "You rely on gold and numerous warriors, I... on the power of God".
The ambassador also transmitted an oral afterword: Rukn ad-Din would make Tamar his wife if she accepted Islam, otherwise he would make her his concubine. Zakaria II Mkhargrdzeli hit the ambassador, and told him: "If you were not an ambassador, it would be proper to cut out your tongue first and then cut off your head" and pointed to the expectation of Rukn ad-Din's divine judgement carried out by Georgians.
