Odissi (ଓଡ଼ିଶୀ) also referred to as Orissi in old literature, oldest surviving classical dance of India, is a major ancient Indian classical dance that originated in the temples of Odisha – an eastern coastal state of India. Odissi, in its history, was performed predominantly by women, and expressed religious stories and spiritual ideas, particularly of Vaishnavism through songs written and composed according to the ragas & talas of Odissi music by ancient poets of the state. Odissi performances have also expressed ideas of other traditions such as those related to Hindu deities Shiva and Surya, as well as Hindu goddesses (Shaktism).
The theoretical foundations of Odissi trace to the ancient Sanskrit text Natya Shastra, its existence in antiquity evidenced by the dance poses in the sculptures of Kalingan temples, and archeological sites related to Hinduism, Buddhism and Jainism. It was suppressed under British Rule. The suppression was protested by the Indians, followed by its revival, reconstruction and expansion since India gained independence from the colonial rule.
