The Neo Buddhist movement (also known as the Buddhist movement For Dalits, Ambedkarite Buddhist movement or Modern Buddhist movement) is a religious as well as a socio-political movement among Dalits in India which was started by B. R. Ambedkar. It 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.
The movement was launched in 1956 by Ambedkar when nearly half a million Dalits – formerly untouchables – joined him and converted to Navayana Buddhism. It rejected Hinduism, challenged the caste system in India and promoted the rights of the Dalit community. The movement also rejected the teachings of Mahayana, Theravada and Vajrayana traditions of Buddhism, instead the movement claims to be a form of engaged Buddhism as taught by Ambedkar.
Buddhism originated in ancient India and grew after Ashoka adopted it. By the 2nd century CE, Buddhism was widespread in India and had expanded outside of India into Central Asia, East Asia and parts of Southeast Asia. During the Middle Ages, Buddhism slowly declined in India, while it vanished from Persia and Central Asia as Islam became the state religion.
According to Randall Collins, Buddhism was already declining in India by the 12th century, but with the pillage by Muslim invaders it nearly became extinct in India. In the 13th century, states Craig Lockard, Buddhist monks in India fled to Tibet to escape Islamic persecution, while the monks in western India, states Peter Harvey, escaped persecution by moving to south Indian Hindu kingdoms that were able to resist the Muslim power.
Efforts to revive Buddhism in India began in the 19th century, such as with the efforts of Sri Lankan Buddhist leader Anagarika Dharmapala who founded the Maha Bodhi Society. The Maha Bodhi Society, according to Bhagwan Das, was not a Dalit movement however, because it mainly attracted upper-caste Hindus to Buddhism.
