Dr. B.R. Ambedkar was a prominent Indian jurist and politician who campaigned against social discrimination of Dalits (formerly known as "untouchables"). He was born into a poor Dalit family and faced significant discrimination early in life. He went on to become independent India's first law minister and had a major role in drafting the country's constitution. He also campaigned vigorously for Dalit and women's rights. Later in life, disillusioned by Hinduism's treatment of Dalits, he converted to Buddhism and encouraged many Dalits to do the same. He passed away in 1956, just days after completing a manuscript on Buddhism.
