The Later Chola dynasty ruled the Chola Empire from 1070 C.E. until the demise of the empire in 1279 C. E. This dynasty was the product of decades of alliances based on marriages between the Cholas and the Eastern Chalukyas based in Vengi, and produced some of the greatest Chola emperors such as Kulothunga Chola I (1070–1120 C. E.). Even though the later Cholas are often referred to as Chalukya Cholas, there were two breaks in the line. Kulothunga Chola II and Rajadhiraja Chola II did not belong to the Chalukya Chola line. Kulottunga II was a grandson of Vikrama Chola and Rajadhiraja Chola II was not the son of Rajaraja Chola II.
