The first 8 years of his reign were utilized by Rajaraja Chola I for organizing and augmenting his army. Since ages, the Pandyas, Cheras and Sinhala were against the Cholas. The first attack was on Chera King Bhaskara Ravi Varman Thiruvadi and in this campaign in Kerala, Rajaraja I destroyed a fleet in the port of Kandalur. However, some sources say that the port was under Pandyas. This conquest led him to assume the title_______________(the wearer of three crowns Chera, Chola and Pandya).
