According to the 13th Jain scholar Abhayatilaka Gani, when Chamundaraja became incapable of governing the kingdom, his sister Vachinidevi appointed Vallabha as the new king.
[1] The 14th century writer Merutunga, on the other hand, claims that Vallabha ascended the throne after his father's death, and ruled for six months.
[1] The 12th century Vadnagar prashasti inscription states that the kings of Malwa were shaken when they heard about Vallabha's marches.
The 13th century writer Abhayatilaka Gani, who wrote a commentary on Hemachandra's work, states that Malwa was the kingdom against which Vallabha marched to avenge the insult against Chamundaraja.
However, his conclusion was based on a particular verse in which Hemachandra states that Vallabha passed by the confluence of the Para and the Sindhu rivers.
[4] The 14th century writer Merutunga embellishes the earlier accounts by claiming that Vallabha not only reached Malwa, but also besieged the Paramara capital Dhara.
[5] Some other works written under Chaulukya patronage, such as Sukrita Sankirtana by Arisimha and Sukrita-Kirti-Kallolini by Udayaprabha, claim that Vallabha defeated the king of Malwa.
