Rajaraja I (Middle Tamil: Rājarāja Cōḻaṉ; Classical Sanskrit: Rājarāja Śōḷa; 3 November 947 – January/February 1014), also known as Rajaraja the Great, was a Chola emperor who reigned from 985 to 1014. He was known for his conquests of southern India and the Anuradhapura kingdom of Sri Lanka, as well as increasing Chola influence across the Indian Ocean. Rajaraja's birth name is variously given as Arul Mozhi Varman
Rajaraja's empire encompassed vast territories, including regions of the Pandya country, the Chera country, and northern Sri Lanka. He also extended his influence over strategic islands such as Lakshadweep, Thiladhunmadulu atoll, and parts of the Maldives in the Indian Ocean. His conquests were not limited to the south; he also launched successful campaigns against the Western Gangas and the Western Chalukyas, extending Chola authority as far as the Tungabhadra River. In the east, Rajaraja faced fierce opposition from the Telugu Chola king Jata Choda Bhima over control of Vengi. This region held significant strategic importance due to its access to resources and trade routes. The conflict between the two rulers intensified as they vied for dominance in the region, resulting in significant battles and shifting allegiances.
