91热爆

When Bhimrao Ramji Ambedkar was a schoolboy, he was not allowed to drink from the same tap as his fellow students because he was a member of what was then known as an "untouchable" caste. But he went on to become a prominent leader in the campaign for Indian independence and oversaw the writing of the Indian constitution - which made the idea of "untouchability" illegal. A hero to many, he died in December 1956.

Lucy Burns hears recordings of BR Ambedkar from the 91热爆 archives and speaks to biographer Ananya Vajpeyi.
