The Pandyan Civil War from 1166 to 1182 was precipitated by rival claims of succession to the Pandyan throne. The Civil War began between Parakrama Pandyan and his nephew Kulasekhara Pandyan and lasted for next 15 years between successive Pandyan kings. The war gradually spread to the rest of Southern India when the Chola King Rajadhiraja II and the Sinhalese King Parakramabahu I of Polonnaruwa entered the fray and took opposing sides in the conflict, eager to increase their influence in the Pandya kingdom.
