History of georgian kings Part.5 David The Builder IV

                                                  
The Qipcaqs were immediately put to use. In 1120, King David twice invaded and defeated Shirwan, then captured the fortresses of Kabala, Kurdevan, Lizan, and Khishtalant. In 1121, while the king was isolated by heavy snow in western Georgia, the Seljuks invaded eastern Georgian provinces but David rallied his forces and the local population to clear the snow-covered road across the Surami (Likhi) Mountains and defeat the invading forces. The Georgian king soon asserted his authority over almost the entire southern Caucasia, except for Tbilisi. He established contact with the Crusaders in the Holy Land, and there is evidence that the two factions tried to coordinate their actions against the Muslims.
