Rajendra I, often referred to as Rajendra the Great, Gangaikonda Cholan, and Kadaram Kondan, was a Chola Emperor who reigned from 1014 and 1044 CE. He was born in Thanjavur to Rajaraja I and his queen Vanathi and assumed royal power as co-regent with his father in 1012 until his father died in 1014, when Rajendra ascended to the Chola throne. During his reign, the Chola Empire reached its zenith in the Indian subcontinent; it extended its reach via trade and conquest across the Indian Ocean, making Rajendra one of only a few Indian monarchs who conquered territory beyond South Asia.

The Chola Empire, which is often referred to as the Imperial Cholas, was a medieval Indian, thalassocratic empire that was established by the Chola dynasty that rose to prominence during the middle of the ninth century and united southern India under their rule.
