Dalit Buddhist movement
The Dalit Buddhist movement (also known as the Neo-Buddhist movement) is a religious as well as a socio-political movement among Dalits in India which was started by B. R. Ambedkar. It radically re-interpreted Buddhism and created a new school of Buddhism called Navayana. The movement has sought to be a socially and politically engaged form of Buddhism.
