Rajaraja Chola I

Rajaraja Chola I transformed the Cholas from a regional Tamil power into an imperial one. He annexed the Chera and Pandya territories, conquered northern Sri Lanka, and extended Chola influence over the Maldives, laying the groundwork for the vast maritime empire his son Rajendra I would later expand. At home, he overhauled land revenue administration through detailed village-level surveys, and his reign produced an extraordinary body of temple inscriptions that remain a primary source for Chola-era social and economic history. His crowning achievement is the Brihadeeswarar Temple (Rajarajeswaram) at Thanjavur, completed in about 1010 CE after roughly seven years of construction — a granite monument with a 66-meter vimana that was, at the time, one of the tallest structures ever built in South Asia. Rajaraja was also a patron of Chola bronze casting and Tamil devotional (Shaiva) hymn compilation, commissioning the first systematic collection of the Nayanmar hymns known as the Tevaram.
