The expedition is believed to have been necessitated by a succession dispute in the Eastern Chalukya kingdom where the claims of Rajaraja Narendra, the son of Vimaladitya, the previous king, and his queen Kundavai, were contested by Vishnuvardana Vijayaditya VII, a son of Vimaladitya through another wife [REF].
Following this victory, Rajendra Chola I led an expedition northwards supported by an advance guard led by Araiyan Rajarajan, to punish the kings of Kalinga and Odda who had sided with Vijayaditya in the succession dispute [REF].
