Rajadhiraja Chola I (994–28 May 1052) was a Chola emperor, as the successor of his father, Rajendra I. He was the only Chola emperor who was killed while leading his army in war, and although he had a short reign, he helped his father conquer several territories as well as to maintain the Chola authority over most of Sri Lanka, Eastern Chalukyas and Kalinga, among others. He also established imperial relations with overseas allies despite a series of revolts in the territory.
Rajadhiraja Chola proved capable of maintaining the vast and expansive empire with territories even outside the shores of India. Records also show that the king was a skilled commander on the battlefield, leading his soldiers from the front lines. He earned the title Jayamkonda Solan (The Victorious Cholan) after numerous victories. Towards the end of his reign, he sacked the Western Chalukyan capital Kalyanapuram and assumed the title Kalyanapuramkonda Chola and performed a Virabhisheka (anointment of heroes) under the name Vijaya Rajendra Cholan (the victorious Rajendra Cholan).
