Bharata Natyam () also spelled Bharatanatyam, is a classical Indian dance form that originated in the temples of Tamil Nadu. This dance form is the product of various 19th- and 20th-century reconstructions of Sadir, the art of temple dancers called Devadasis. It was described in the treatise Natya Shastra by Bharata around the beginning of the common era. Bharata Natyam is known for its grace, purity, tenderness, expression and sculpturesque poses. Lord Shiva is considered the God of this dance form. Today, it is one of the most popular and widely performed dance styles and is practiced by male and female dancers all over the world.
