Rajendra Chola II reigned as the Chola king succeeding his elder brother Rajadhiraja Chola in the 11th century. He is best remembered for his role in the battle of Koppam along with his elder brother where he dramatically turned the tables on the Chalukyan King Someshvara I, after the death of his brother in 1052. During his early reign an expedition was led to Sri Lanka, in the course of which the Sri Lanka army was routed and their king Vijayabahu I of Polonnaruwa was driven to take refuge in a mountain-fortress. He maintained the Chola Empire well as the distribution of his records show that the Chola Empire did not suffer any loss of territory during his reign.
