Sattras are monastic institutions created as part of the 16th century Neo-Vaishnavite reformist movement started by Vaishnavite saint-reformer SrimantaSankaradeva (1449-1596).
As the saint travelled across Assam, spreading his teachings and propagating an egalitarian society, these Sattras/Thans were established as centres of religious, social and cultural reforms in the 16th century.
Today, Sattras are spread across the state, promulgating Sankardeva’s unique “worship through art” approach with music (borgeet), dance (xattriya) and theatre (bhauna). During the Ahom reign, the Sattras received a lot of donations in the form of land or money from the kings.
