Rajaraja I

Rājarāja I (Middle Tamil: Rājarāja Cola; 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 and Arulmoli 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.

Rajaraja I commissioned the construction of the Rajarajeshwaram Temple in the Chola capital of Thanjavur, revered as one of the most prominent examples of the medieval South Indian architectural style. Additionally, during his reign, important Tamil literary works by poets such as Appar, Sambandar, and Sundarar were gathered and compiled into a single collection known as the Thirumurai. This earned him the title of 'Thirumurai Kanda Cholar' (lit. 'The One Who Found Thirumurai'). He initiated a project of land survey and assessment in 1000 which led to the reorganisation of Tamil country into individual units known as valanadus. Rajaraja died in 1014, and was succeeded by his son Rajendra Chola I.
