at Kogali respectively, Jayasimha was defeated in Kadambalige, Ahavamalla Someshwara I suffered defeats many a time at the hands of Rajadhiraja Chola, and lost his brother Jayasingan in battle with Rajendra Chola II. After Rajadhiraja Chola I and Rajendra Chola II, their brother Virarajendra Chola defeated Ahavamalla Someshwara I on not less than five occasions. Virarajendra Chola also put to flight the latter's two sons, Vikkalan (Vikramaditya VI) and Singanan (Jayasimha III), multiple times in the battles of Kudala sangama. Virarajendra Chola also defeated the eldest son of Ahavamalla Someshwara I, and crown-prince Someshwara II in Kampili, and spoiled his coronation ceremony. Ahavamalla Someshwara I seems to have died in the reign of Virarajendra Chola as there is no mention of him in Kulottunga's records. This is evident from a record of Virarajendra Chola, who in his fifth year states that unable to bear the disgrace of his earlier defeats, Ahavamalla Someshwara I wrote a letter to the Chola calling for war, but in the end never showed up and instead fled and plunged himself into the ocean. This is conceded in Bilhana's Vikramakadevacarita, a work on the life of Vikramaditya VI who claims that Ahavamalla Someshwara I died around this time by committing ritual suicide by drowning himself in the Tungabhadra. Upon his father's death, Vikramaditya VI approached Virarajendra and sued for peace and the Chola agreed as he saw in him an ally to counter and nullify the crown-prince Someshvara II. Accordingly, the Chola offered his daughter's hand in marriage, bestowed upon him the Rattapadi-seven-and-a-half-lakh country and made him the Vallabha (Chalukyan king). Vikramaditya readily accepted the deal for he had his own plans to overthrow his elder brother, which he would eventually accomplish and then usurp the throne. There was also another contender, Vijayaditya, on whom Virarajendra had bestowed Vengi towards the end of his reign. Some historians identify this Vijayaditya with the Eastern Chalukyan prince and half-brother of Rajaraja Narendra while others like Venkayya suggest that this person was yet another younger brother of Vikramaditya VI. That this Vijayaditya was an ally of Vikramaditya VI is evident from an inscription of Rajadhiraja Chola I. So at the end of Virarajendra's reign, Kulottunga found himself facing Vikkalan (Vikramaditya VI), the latter's younger brother Singanan (Jayasimha), their elder brother Someshwara II and their younger brother or ally Vijayaditya. It was clear from the time Kulottunga ascended the throne
