During his reign Someshvara II was constantly under threat from his more ambitious younger brother Vikramaditya VI.
Around 1070 AD Someshvara II expanded his empire and brought Malava under his control.
The Chola army invaded the Chalukya country and laid a siege to the town of Gutti in (Kurnool district) and attacked Kampili.
Vikramaditya saw the opportunity presented by the confusion in the kingdom due to the Chola invasion.
Vikramaditya seduced Someshvara's feudatories from their loyalty towards the monarch, and with their aid, entered into negotiations with the Chola king Virarajendra.
