Wikipedia (i/ˌwɪkᵻˈpiːdiə/ or i/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a free-access, free-content Internet encyclopedia, supported and hosted by the non-profit Wikimedia Foundation. Those who can access the site can edit most of its articles. Wikipedia is ranked among the ten most popular websites, and constitutes the Internet's largest and most popular general reference work.
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger coined its name, a portmanteau of wiki and encyclopedia. Initially only in English, Wikipedia quickly became multilingual as it developed similar versions in other languages, which differ in content and in editing practices. The English Wikipedia is now one of 291 Wikipedia editions and is the largest with 5,081,662 articles (having reached 5,000,000 articles in November 2015). There is a grand total, including all Wikipedias, of over 38 million articles in over 250 different languages. As of February 2014, it had 18 billion page views and nearly 500 million unique visitors each month.
An encyclopedia or encyclopaedia (also spelled encyclopædia, see spelling differences) is a type of reference work or compendium holding a comprehensive summary of information from either all branches of knowledge or a particular branch of knowledge. Encyclopedias are divided into articles or entries, which are usually accessed alphabetically by article name. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, unlike dictionary entries, which focus on linguistic information about words, encyclopedia articles focus on factual information concerning the subject for which the article is named.
Encyclopedias have existed for around 2,000 years; the oldest still in existence, Naturalis Historia, was written starting in ca. AD 77 by Pliny the Elder and was not fully revised at the time of his death in AD 79. The modern encyclopedia evolved out of dictionaries around the 17th century. Historically, some encyclopedias were contained in one volume, whereas others, such as the Encyclopædia Britannica, the Enciclopedia Italiana (62 volumes, 56,000 pages) or the world's largest, Enciclopedia universal ilustrada europeo-americana (118 volumes, 105,000 pages), became huge multi-volume works. Some modern encyclopedias, such as Wikipedia, are electronic and often freely available.
Bhimrao Ramji Ambedkar ([bʱiːmraːw raːmdʑiː aːmbeːɽkər]; 14 April 1891 – 6 December 1956), popularly known as Babasaheb, was an Indian jurist, economist, politician and social reformer who inspired the Modern Buddhist Movement and campaigned against social discrimination against Untouchables (Dalits), while also supporting the rights of women and labour. He was Independent India's first law minister and the principal architect of the Constitution of India.
Ambedkar was a prolific student, earning a law degree and various doctorates from Columbia University and the London School of Economics, and gained a reputation as a scholar for his research in law, economics and political science. 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.
