Kulottunga I (;1025 CE - 1122 CE) also spelt Kulothunga (), was a Chola Emperor who reigned from 1070 CE to 1122 CE succeeding his cousin Athirajendra Chola. He also served as the Eastern Chalukya king from 1061 CE to 1118 CE, succeeding his father Rajaraja Narendra. His birth name was Rajendra. He is related to the Chola dynasty through his mother's side and the Eastern Chalukyas through his father's side. His mother, Ammangaidevi, was a Chola princess and the daughter of emperor Rajendra I. His father was king Rajaraja Narendra of the Eastern Chalukya dynasty who was the nephew of Rajendra I and maternal grandson of Rajaraja I. According to historian Sailendra Nath Sen, his accession marked the beginning of a new era and ushered in a period of internal peace and benevolent administration. Kulottunga had diplomatic relations with the north Indian city Kanauj and also with distant countries like Cambodia, Srivijaya, Khmer, Pagan (Burma) and China. He established Chola overlordship over the Srivijayan province of Kedah in Malay Peninsula. An inscription in a Taoist temple in Guangzhou, dated to 1079 CE, declares Kulottunga, King of Chulien (Chola) to be the supreme chief of the Land of San-fo-tsi (Srivijaya). According to Tan Yeok Seong, the editor of the inscription, Kulottunga ruled both the Chola and Srivijayan kingdoms. In the small Leyden grant that is dated to 1090 CE, the king of Kadaram (Srivijaya) is mentioned as a vassal of Kulottunga. Like his predecessors, Kulottunga was a patron of arts and literature and the much celebrated Tamil poem Kalingattuparani was composed during his rule by poet Jayamkondaan who lived in his court. His records also testify to the highly organised system of fiscal and local administration. During his reign Kulottunga carried out a massive land survey that formed the basis for taxation. Kulatunga died around 1122 CE around the age of 97, although this is disputed. This makes him one of the longest living monarchs in the Middle Ages. He was succeeded by his son Vikrama Chola. According to historian Nilakanta Sastri, Kulottunga avoided unnecessary wars and evinced a true regard for the well-being of his subjects. He had a long and prosperous reign characterized by unparalleled success that laid the foundation for the well being of the empire for the next 150 years. Birth and early life Kulottunga was born under the star of Pusya around 1025 CE .
