Sattriya or Sattriya Nritya, is a major Indian classical dance. It is a dance-drama performance art with origins in the Krishna-centered Vaishnavism monasteries of Assam, and attributed to the 15th century Bhakti movement scholar and saint named Srimanta Sankardev.
One-act plays of Sattriya are called Ankiya Nat, which combine the aesthetic and the religious through a ballad, dance and drama. The plays are usually performed in the dance community halls of monastery temples (sattras). The themes played relate to Krishna and Radha, sometimes other Vishnu avatars such as Rama and Sita.
Recognized in 2000 as a classical dance by Sangeet Natak Akademi of India, modern Sattriya explores many themes and plays, and its performances staged worldwide.
