Kambar or Kavichakravarthy Kamban (1180 CE–1250 CE) was an Indian Tamil poet and the author of the Ramavataram, popularly known as Kambaramayanam, the Tamil version of the epic Ramayana. Kambar also authored other literary works in Tamil, such as Thirukkai Vazhakkam, Erezhupathu, Silaiyezhupathu, Kangai Puranam, Sadagopar Anthathi and Saraswati Anthathi.
Kambar was born in Therazhundur. His father was a wealthy farmer named Sadaiyepa Vallal. He grew up the Chola Empire under the reign of Kulothunga III. Having heard of this talented bard, Kulothunga summoned him to his court and honoured him with the title Kavi Chakravarty (The Emperor of Poets).
Kambar flourished in Therazhundur, a village in the culturally rich Nagapattinam District in the modern state of Tamil Nadu in South India.
Kambar is generally dated after the vaishnavite philosopher, Ramanuja, as the poet refers to the latter in his work, the Sadagopar Andhadhi.
Kamban was a great scholar of both Tamil and Sanskrit—two of India's oldest and richest languages in terms of literary works. In a scholarly biography, Kavichakravarty Kamban, Mahavidwan R. Raghava Iyengar wrote in detail about Kambar.
Kambar spent his last days in Nattarasankottai (known for Kannathal temple) near to Sivagangai town and his tomb is situated there. It is said that Kambar after having differences with Kulothunga's son, Rajaraja III, he left the Chola kingdom and moved from place to place. When he reached at Nattarasankottai, he was very thirsty and asked water in one house at Nattarasankottai. He was offered buttermilk in return and he became very happy and decided to stay there itself and spent his last days there. He lived there till his death. There is tomb in Nattarasankottai and every year a celebration called Kamban vizha is conducted at this place to felicitate Kambar.
