In India, under the leadership of Dr. Bhimrao Ambedkar, lower castes embraced Buddhism in the 1950s as a form of protest against deeply embedded Hindu traditions of social inequality by birth.
Today a section of the population in the Indian state of Maharashtra, the area in which Dr. Ambedkar lived, still follow “neo-Buddhism,” in other words a revived Buddhism.
The main organization in India that has advocated for these neo-Buddhists (since 1956) is the Trailokya Mahasangh.
