Ambedkar was a prolific student, earning doctorates in economics from both Columbia University and the London School of Economics, and gained a reputation as a scholar for his research in law, economics and political science.[10] 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.[11]
In 1990, the Bharat Ratna, India's highest civilian award, was posthumously conferred upon Ambedkar. Ambedkar's legacy includes numerous memorials and depictions in popular culture. Tipu Sultan (born Sultan Fateh Ali Sahab Tipu,[2] 20 November 1750 – 4 May 1799), also known as the Tiger of Mysore and Tipu Sahib,[3] was a ruler of the Kingdom of Mysore. He was the eldest son of Sultan Haidar Ali of Mysore.[4] Tipu introduced a number of administrative innovations during his rule, including his coinage, a new Mauludi lunisolar calendar,[5] and a new land revenue system which initiated the growth of the Mysore silk industry.[6] Tipu expanded the iron-cased Mysorean rockets and commissioned the military manual Fathul Mujahidin, and is considered a pioneer in the use of rocket artillery;[7] Tipu Sultan deployed the rockets against advances of British forces and their allies during the Anglo-Mysore Wars, including the Battle of Pollilur and Siege of Seringapatam. He also embarked on an ambitious economic development program that established Mysore as a major economic power, with some of the world's highest real wages and living standards in the late 18th century.[8]
