The Spanish Wikipedia (Spanish: Wikipedia en español) is a Spanish-language edition of Wikipedia, a free, online encyclopedia. It has 1,023,908 articles. Started in May 2001, it reached 100,000 articles on March 8, 2006 and 1,000,000 articles on May 16, 2013. It is the 6th largest Wikipedia as measured by the number of articles. On May 17, 2013 the Spanish Wikipedia reached one million articles.
In February 2003, many participants of the edition did not agree with the (later rejected) proposal to finance Wikipedia through advertising, and broke away to establish the Enciclopedia Libre fork. After the spin-off, the Spanish Wikipedia had very little activity until the upgrade to the Phase III of the software, later renamed MediaWiki, when the number of new users started to increase again. Both projects continue to co-exist, but the Spanish Wikipedia is by far the more active of the two.

Size and users
It has the second largest number of users, after the English Wikipedia. However, it is ranked seventh for number of articles, below other Wikipedias devoted to languages with smaller numbers of speakers, such as German, French, Dutch, Italian and Russian. In terms of quality, parameters such as article size (over 2 KB: 40%) show it as the second out of the ten largest Wikipedias after the German one. As of October 2012, Spanish Wikipedia is the fourth Wikipedia in terms of the number of edits,  as well as the third Wikipedia by the number of page views.
By country of origin, by September 2006, Spain was the main contributor to the Spanish Wikipedia (39.2% of edits). It is followed by Argentina (10.7%), Chile (8.8%), the Netherlands (8.4%), Mexico (7.0%), Venezuela (5.1%), Peru (3.5%), the United States (3.1%), Colombia (2.7%), Uruguay (1.3%) and Germany (1.1%).
Usage in Spain
Following a study by Netsuus (online market analysis enterprises) on the use of Wikipedia in Spain, it was revealed that most users consult Spanish Wikipedia (97%) compared to Wikipedias in other regional languages (2.17% for Wikipedia in Catalan, 0.64% in Galician and 0.26% in Basque)
Differences from other Wikipedias
- The Spanish Wikipedia only accepts free images, and has rejected fair use since 2004, after a public vote. In 2006, it was decided to phase out the use of local image uploads and to exclusively use Wikimedia Commons for images and other media in the future.
- Unlike the French and English Wikipedias, the Spanish Wikipedia did not have an Arbitration Committee until January 2007. It comprises seven members, chosen by public vote.
- Some templates, like the navigation templates, have been deprecated.
- Terminology in Spanish: The equivalent to the English Wikipedia's featured articles and good articles are artículos destacados and artículos buenos respectively. Also, following a vote on August 2004, administrators in the Spanish Wikipedia took the name of bibliotecarios (librarians in English). Other discarded options were usuarios especiales (special users) or basureros (janitors).
- There is no autoconfirmation, in order to move pages and edit semi protected articles, one must request for these permissions, much like, requests for adminship on the English Wikipedia 
A comparative study by the Fundación Colegio Libre de Eméritos Universitarios, made by Prof. Arias Maldonado (University of Malaga) and published in 2010, comparing some articles with those of the English and German Wikipedia, concludes that the Spanish version of Wikipedia is the least reliable of the three, more cumbersome and imprecise than the German and English Wikipedias, usually lacking reliable sources with many unreferenced data, and too dependent on online references.
During Wikimania 2009, free-software activist Richard Stallman criticized the Spanish Wikipedia for restricting links to the Rebelion.org left-wing web site and allegedly banning users who had complained about what had happened. Participants in the Spanish Wikipedia responded that Rebelion.org is primarily a news aggregator, that links to aggregators should be replaced with links to original publishers whenever possible, and that they considered the issue to be one of spam.
