Politics of succession erupted again over the Vengi throne in c.1061 after the death of the Eastern Chalukya King Rajaraja Narendra. Someshvara I installed Saktivarman II, son of Vijayaditya II, on the throne. This went against the wishes of the Cholas who wanted their own blood line from the Vengi family at the helm. The Cholas desired to crown Rajendra, son of the deceased king Rajaraja Narendra. There was a brief respite for Someshvara I over Vengi affairs but the new Chola monarch Rajendra II appears to have defeated Someshvara I in several encounters, including in a major battle at Kudalasangama (modern Koodli in the Shimoga district) in c.1062. The historians Chopra et al., claim this Kudalasangama was actually at the confluence of Krishna and Tungabhadra rivers. On this occasion, Someshvara I had sent two armies, one under his general Chamundaraya and another into Gangavadi (southern Mysore territory) under his sons prince Vikramaditya VI and Jayasimha. However, Rajendra II defeated both armies and thus Someshvara I's effort to erase the defeat at Koppal failed. In c.1063, Rajendra II and his son Rajamahendra died leading to the coronation of Virarajendra as the new Chola king.
