The details of the king's family and parentage are available from a number of grants and plates like the one from Chelluru(a village in Rayavaram Mandalam of Konaseema district ) that was issued by his son, prince Vira Chola, and from literary works, such as the famous poem Kalingattupparani. Kulottunga was the maternal grandson of Emperor Rajendra Chola I through the latter's daughter Ammangadevi. His father was the Eastern Chalukya king Rajaraja Narendra who himself was the son of Kundavai, the younger sister of Rajendra Chola I and the daughter of Rajaraja I. Rajaraja Narendra married princess Ammangadevi, the daughter of his maternal uncle, Rajendra Chola I of the solar race. The latter is described as "the ornament of the race of the sun" in the Chellur plates of Vira Chola. The poem Kalingattuparani gives the details of Kulottunga's birth in the canto "Avataram" (incarnation), wherein his mother is described as belonging to the solar race and his father to the lunar race. Kulottunga is described as an avatar of the Hindu god Vishnu in the canto. An excerpt from the poem reads: Vishnu appeared again in the royal womb of the queen of him of the race of the moon which dispels all darkness, ... Rajaraja's gracious Lakshmi (queen) who was of the rival race of the sun. As a Chola prince he conquered the Sri Vijaya province Kedah and Chakrakota province (Bastar-Kalahandi district-Koraput region) on behalf of his maternal uncle, emperor Virarajendra Chola, in the 11th century. Accession According to the Tamil poem Kalingattuparani, Kulottunga was brought up in the court of Rajendra Chola I in Gangaikondacholapuram. During his youth, Kulottunga participated in many wars, serving alongside both Rajendra Chola I and his successors, Rajadhiraja I, Rajendra Chola II and Virarajendra Chola. During this period, he engaged in the northern campaigns of the empire in and around Sakkarakottam and Vayiragaram where he secured several victories and proved his mettle in warfare. The Sakkarakottam area is identified with the present day Bastar-Kalahandi district-Koraput region which together formed the Chakrakota province back in medieval times. According to Kalingattuparani, it was around this time that Mannar-Mannavan, that is, the "king of kings", suddenly died and the empire was thrown into a state of anarchy until Abhaya, that is Kulottunga, returned and restored order. The Teki, Chellur and Pithapuram grants of Kulottunga's sons, dated in the 17th, 21st and 23rd years of
