Explanation:

The Sattriya dance form was introduced in the 15th century A.D by the great Vaishnava saint and reformer of Assam, Mahapurusha Sankaradeva as a powerful medium for propagation of the Vaishnava faith. The dance form evolved and expanded as a distinctive style of dance later on. This neo-Vaishnava treasure of Assamese dance and drama has been, for centuries, nurtured and preserved with great commitment by the Sattras i.e. Vaishnava maths or monasteries. Because of its religious character and association with the Sattras, this dance style has been aptly named Sattriya.
