Kopperunchinga II (reigned c. 1243-1279 CE) was a Kadava chieftain, who succeeded his father Kopperunchinga I and continued his successes against the Hoysalas. Since the Chola power no longer constituted a threat, Kopperunchinga II acted as the de facto protector of the Chola king and helped him maintain his position on the throne. As he expanded his territorial holdings, Kopperunchinga II assumed such titles as Maharajasimha, Khadgamalla, Kadava Pallava, Alappirandan, Avaniyalappirandan, Kanakasabhapathy, etc. He has left numerous inscriptions mainly in the South Arcot and Chingleput districts and the northern portion of Thanjavur, and a few have also been found in the North Arcot and Chittoor districts. Ultimately, however, the resurgence of the power of the Pandya kingdom of Madurai ended Kopperunchinga's reign and the Kadava dynasty.
Kopperunchinga II followed his father to the throne in the early months of 1243 CE. His residence was at Sendamangalam, where his father had established the Kadava capital. At the outset of his reign, his lands extended from Kanchipuram in the north to near Kumbakonam in the south. The territories north of Kanchipuram and the remaining parts of ancient Tondaimandalam up to Tiruvenkadam (modern day Tirupathi) were conquered during his reign. (In an inscription Kopperunchinga claims to have created a sea of blood from the bodies of his slain enemies.)
The political situation of the Tamil country was at first very favourable for Kopperunchinga II not only to continue the consolidation of the Kadava territories but to expand them. The Kadavas' main adversary, the Hoysalas, had fought the Kadava army in many battles during Kopperunchinga I's reign; but in Kopperunchinga II's time, his Hoysala contemporary Somesvara II stayed away from the Tamil country, as he was busy maintaining his own precarious position at home.
