Aditya I
Aditya I (c. 870 – c. 907 CE), the son of Vijayalaya, was the Chola king who extended the Chola dominions by the conquest of the Pallavas and occupied the Western Ganga Kingdom.
Pallava Civil War
During the invasion of the Chola country, the Pandya king Varagunavarman II became an ally of Nripatunga, the eldest son of the Pallava King Nandivarman III.
When Nandivarman died in 869 CE differences arose between Nripatunga and his stepbrother Aparajita, probably owing to the latter’s ambition to rule the kingdom on his own right. Both sides looked for allies. Nripatunga continued to have Varaguna Pandya by his side while Aparajita allied with the Ganga king Prithvipathi I and with Aditya Chola I.
The rival armies met at Thirupurambiyam near Kumbakonam c. 885 CE. The armies of Pandyas and Nripatunga Pallava were routed by Aparajita Pallava and Aditya I Chola.
Aditya I’s ascendancy
Although the victor of the Thirupurambiyam battle was Aparajita, the real gains went to Aditya I Chola. This battle ensured the end of Pandya power in the south. Pandya Varagunavarman renounced his throne and turned an ascetic. The grateful Aparajita not only allowed Aditya I Chola to keep the territories won by Vijayalaya Chola, but also to add new territories from the defeated Pandyas.
