Srimanta Sankardev was a 15th–16th century Assamese polymath; a saint-scholar, poet, playwright, dancer, actor, musician, artist social-religious reformer and a figure of importance in the cultural and religious history of Assam, India. He is credited with building on past cultural relics and devising new forms of music (Borgeet), theatrical performance, dance (Sattriya), literary language (Brajavali). Besides, he has left a literary oeuvre of trans-created scriptures, poetry and theological works written in Sanskrit, Assamese and Brajavali. The Bhagavatic religious movement he started, Ekasarana Dharma and also called Neo-Vaishnavite movement, influenced two medieval kingdoms – Koch and the Ahom kingdom – and the assembly of devotees he initiated evolved over time into monastic centers called Sattras, which continue to be important socio-religious institutions in Assam and to a lesser extent in North Bengal. Sankardev inspired the Bhakti movement in Assam just as Guru Nanak, Ramananda, Namdev, Kabir, Basava and Chaitanya Mahaprabhu inspired it elsewhere in the Indian subcontinent.
