Bhimrao Ramji Ambedkar April,popularly also known as Babasaheb, was an Indian jurist,political leader,philosopher, anthropologist,historian,orator,economist,teacher,and editor.He was also the Chairman of the Drafting Committee of Indian Constitution. In 2012 he was chosen greatest Indian in a nationwide poll held by History TV and CNN-IBN.Born into a poor Mahar (considered an Untouchable caste) family, Ambedkar campaigned against social discrimination, the system of Chaturvarna – the categorization of Hindu society into four varnas – and the Hindu caste system. He converted to Buddhism and is also credited with providing a spark for the transformation of hundreds of thousands of Dalits or untouchables to Theravada Buddhism. Ambedkar was posthumously awarded the Bharat Ratna, India's highest civilian award,in 1990.Overcoming numerous social and financial obstacles,Ambedkar became one of the first Dalit (untouchable) to obtain a college education in India. Eventually earning law degree and doctorates for his study and research in law,economics and political science from Columbia University and the London School of Economics,Ambedkar gained a reputation as a scholar and practiced law for a few years,later campaigning by publishing journals advocating political rights and social freedom for India's untouchables. Mahatma Gandhi and Ambedkar often clashed because Ambedkar sought to remove the Dalits out of the Hindu community, while Gandhi tried to save Hinduism by exorcising untouchability. Ambedkar complained that Gandhi moved too slowly, while Hindu traditionalists said Gandhi was a dangerous radical who rejected scripture. Guha noted in 2012 that, "Ideologues have carried these old rivalries into the present,with the demonization of Gandhi now common among politicians who presume to speak in Ambedkar’s name."[6] Guha adds that their work complemented each other,and Gandhi often praised Ambedkar.
