Untouchability is certainly an Indian phenomenon. There might be some variations in its intensity and forms, depending on regional, historical and social background.
Untouchables were known by different names in different centuries. In the ancient period, they were called ‘Chandalas’. All those names were contemptuous and degenerative. Some of the names are used even today as abusive words, even though it is a criminal offense. In the 1930s, with a view to remove the contempt in the names, Gandhiji gave the Untouchables a new name ‘Harijans’. It means children of God. He made that name popular.
But the untouchable groups and their leaders gave them their own name ‘Dalits’. Today this name is widely used. ‘Dalit’ means suppressed. Dr. Ambedkar never used this name. But the echo of his philosophy and his Empowering Movement is heard in this name. In the 1970s, during the Jati revolts in Bombay, the word ‘Dalit’ received great popularity. The Dalit Panthers was a revolutionary group from Western India and they used this name to uphold their being and individuality.
