In the late 12th century, Palakatsio formed a fringe of the Javakheti principality. Later, it was part of the Samtskhe-Saatabago. In 1578, the Ottomans captured the region and established the Childir Liva (Liva-i Çıldır), part of the Georgian Vilayet (Vilayet-i Gürcistan), on this land.გურჯისტანის ვილაიეთის დიდი დავთარი: გამოკვლევა: წიგნი III), Sergi Jikia, Tbilisi, 1947-1958, 3 volumes, volume III (1958), p. 379.
