The second half of the 11th century was marked by the strategically significant invasion of the Seljuq Turks, who by the end of the 1040s had succeeded in building a vast empire including most of Central Asia and Persia. The Seljuqs made their first appearances in Georgia in the 1060s, when the Sultan Alp Arslan laid waste to the south-western provinces of the Georgian kingdom and reduced Kakheti. These intruders were part of the same wave of the Turkish movement which inflicted a crushing defeat on the Byzantine army at Manzikert in 1071.[3]
