Kanagasabai Subburathnam, popularly known as Bharathidasan, was a 20th-century Tamil poet and writer rationalist whose literary works handled mostly socio-political issues. He was deeply influenced by the Tamil poet Subramania Bharati and named himself as Bharathidasan. His writings served as a catalyst for the growth of the Dravidian movement in Tamil Nadu. In addition to poetry, his views found expression in other forms such as plays, film scripts, short stories and essays. The Government of Puducherry union territory has adopted the song of Invocation to Mother Tamil, written by Bharathidasan as the state song of Puducherry. (Tamil Thai Valthu (Puducherry))
