Somesvara’s successor, his eldest son Somesvara II, feuds with his younger brother, Vikramaditya VI, an ambitious warrior who had initially been governor of Gangavadi in the southern Deccan.

Married to a Chola princess (a daughter of Virarajendra Chola), Vikramaditya VI maintains a friendly alliance with them.

After the death of the Chola king in 1070, Vikramaditya VI invades the Tamil kingdom and installs his brother-in-law, Adhirajendra, on the throne, creating conflict with Kulothunga Chola I, the powerful ruler of Vengi, who seeks the Chola throne for himself.
