Ambedkar graduated from Elphinstone College, University of Bombay, and studied economics at Columbia University and the London School of Economics, receiving doctorates in 1927 and 1923 respectively and was among a handful of Indian students to have done so at either institution in the 1920s. He also trained in the law at Gray's Inn, London. In his early career, he was an economist, professor, and lawyer. His later life was marked by his political activities; he became involved in campaigning and negotiations for India's independence, publishing journals, advocating political rights and social freedom for Dalits, and contributing significantly to the establishment of the state of India. In 1956, he converted to Buddhism, initiating mass conversions of Dalits.In 1990, the Bharat Ratna, India's highest civilian award, was posthumously conferred on Ambedkar. The salutation Jai Bhim (lit. "Hail Bhim") used by followers honours him. He is also referred to by the honorific Babasaheb (BAH-bə SAH-hayb).
