Swami Vivekananda (Bengali: [ʃami bibekanɔndo] (About this soundlisten); 12 January 1863 – 4 July 1902), born Narendranath Datta (Bengali: [nɔrendronatʰ dɔto]), was an Indian Hindu monk. He was a chief disciple of the 19th-century Indian mystic Ramakrishna.[4][5] He was a key figure in the introduction of the Indian philosophies of Vedanta and Yoga to the Western world,[6][7] and is credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the late 19th century.[8] He was a major force in the contemporary Hindu reform movements in India, and contributed to the concept of nationalism in colonial India.[9] Vivekananda founded the Ramakrishna Math and the Ramakrishna Mission.[7] He is perhaps best known for his speech which began with the words "Sisters and brothers of America ...,"[10] in which he introduced Hinduism at the Parliament of the World's Religions in Chicago in 1893.
