(Tamil: திருவள்ளுவர்) is a celebrated Tamil poet and philosopher whose contribution to Tamil literature is the Thirukkural, a work on ethics. As with most other details about Valluvar, the exact place of his birth remains uncertain. Thiruvalluvar is thought to have lived sometime between the 3rd century BC and the 1st century BC.
The Tamil poet Mamulanar of the Sangam period mentioned that Thiruvalluvar was the greatest Tamil scholar and Mamulanar also mentioned the Nanda Dynasty of northern which ruled until the 4th century BC. This estimate is based on linguistic analysis of his writings, as there is no archaeological evidence for when he lived. He is sometimes also called Theiva Pulavar ("Divine Poet"), Valluvar, Poyyamozhi Pulavar, Senna Pothar,Gnana Vettiyan or Ayyan.
