Aditya I
Aditya Chola I was a Chola king who reigned in the late ninth to early tenth century CE. He was the son of Vijayalaya Chola, and laid the foundation of the Medieval Cholas with the conquest of the Pallava Kingdom and the occupation of the Western Ganga Kingdom and Kongu Nadu. Aditya Chola I was succeeded by his eldest son Parantaka Chola I.
Battle of Thirupurambiyam
In 878 CE, Pandyan king Varagunavarman II invaded the Chola country, which was under the influence of the Pallavas. In the battle held at Thirupurambiyam, he was opposed by Aparajita, the son of Nriputungavarman, and was joined by Aditya Chola and Western Ganga king Prithvipati I. The Pandyas were defeated although Prithvipati was killed in the battle. The Cholas gained certain territories from the Pallavas for the help in the battle.
Conquest of Tondaimandalam and Kongu Nadu
Aditya Chola I planned to overthrow the Pallavas, and invaded Tondai Nadu in 897 CE. He killed king Aparajita in the battle, and the Pallava kingdom became part of Chola territory. The Western Ganga king Prithvipati II acknowledged the suzerainty of Aditya Chola. He conquered the Kongu Nadu region, which was under the suzerainty of the Pandya king Parantaka Viranarayanan.
