# Spanish Wikipedia

The Spanish Wikipedia (Spanish: Wikipedia en español) is the Spanish-language edition of Wikipedia, a free online encyclopedia. It has 2,015,693 articles. Started in May 2001, it reached 100,000 articles on 8 March 2006, and 1,000,000 articles on 16 May 2013. It is the 8th-largest Wikipedia as measured by the number of articles and has the 4th-most edits. It also ranks 32nd in terms of article depth among Wikipedias.
Academic studies have indicated that the Spanish Wikipedia is less reliable than the English and German Wikipedias, as well as more prone to disinformation from Russian government outlets. It has also been criticized for whitewashing left-wing authoritarian regimes such as Cuba's and for allowing damaging disinformation about living people who are critical of the left.

## History

In February 2002, Larry Sanger wrote an e-mail to a mailing list stating that Bomis was considering selling advertisements on Wikipedia. Edgar Enyedy, a user on the Spanish Wikipedia, criticized the proposal. Jimmy Wales and Sanger responded by saying that they did not immediately plan to implement advertisements, but Enyedy began establishing a fork. Enciclopedia Libre was established by 26 February 2002. Enyedy persuaded most of the Spanish Wikipedians into going to the fork. By the end of 2002, over 10,000 articles were posted on the new site, and the Spanish Wikipedia was inactive for the rest of the year. Andrew Lih wrote that "for a long time it seemed that Spanish Wikipeda [sic] would be the unfortunate runt left from the Spanish fork." The general popularity of Wikipedia attracted new users to the Spanish Wikipedia who were unfamiliar with the fork and these users came by June 2003. By the end of that year the Spanish Wikipedia had over 10,000 articles. The size of the Spanish Wikipedia overtook that of the fork in the last months of 2004.
Lih stated in 2009 that the concepts of advertising and forking were still sensitive issues for the Wikipedia community because "It took more than a year for the Spanish Wikipedia to get back on its feet again" after the fork had been initiated.
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.

The Spanish Wikipedia has the second most registered users, after the English Wikipedia, and the fifth most active users, after the English, French, German and Japanese Wikipedias. It ranks among the worse Wikipedias in retention of new editors and has one of the highest edit revert rates. The Spanish Wikipedia has the second lowest number of administrators per active editors (0.38%), behind the Japanese edition.
It is ranked eighth for number of articles, below other Wikipedias devoted to languages with smaller numbers of speakers, such as German, French, Cebuano, Dutch and Russian. In 2009, the percentage of articles whose size was above 2 KB was 40%, placing the Spanish Wikipedia as the second out of the ten largest Wikipedias after the German one. As of October 2012, the Spanish Wikipedia was the fourth Wikipedia in terms of the number of edits. As of December 2024, it is the sixth Wikipedia by the number of page views, behind the English, Japanese, Russian, German and French Wikipedias.
By country of origin, by September 2017, Spain was the main contributor to the Spanish Wikipedia (39.2% of edits). It was 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%). Note that a number of bots are hosted in the Netherlands.
Among the countries where Spanish is either an official language or a de facto national language, Argentina, Chile, Mexico, Spain and Venezuela have established local chapters of the Wikimedia Foundation.

### Usage in Spain

Following a 2007 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 does not have an Arbitration Committee. A local version was created in January 2007 (comprising seven members, chosen by public vote), and dissolved in 2009 after another vote.
* Some templates, like the navigation templates, have been deprecated, being the only Wikipedia where it is forbidden to use these templates, instead relying on categories that perform the same function.
* Terminology in Spanish:
** The equivalent to the English Wikipedia's featured articles and good articles are artículos destacados and artículos buenos, respectively.
** Following a vote in August 2004, administrators on the Spanish Wikipedia took the name of bibliotecarios (librarians). Other discarded options were usuarios especiales (special users) or basureros (janitors).
* The majority of edits done by unregistered users are reverted by bots targeting edits that are considered vandalism. Due to this, there were proposals and community votes to let the Spanish Wikipedia disable edits from unregistered users similarly to the Portuguese Wikipedia, but these have not been officially implemented.
* In 2023, after a community vote that lasted from August 1 to August 15, the Spanish Wikipedia enabled a bot policy using ORES that reverts edits to rate good faith edits using the y-parameters provided by the platform available under MIT License.

## Evaluation and criticism
### Academic studies

A comparative study by the Colegio Libre de Eméritos, made by Manuel Arias Maldonado (University of Málaga) and published in 2010, compared some articles with those of the English and German Wikipedias. It concluded that the Spanish version of Wikipedia was the least reliable of the three. It found it to be more cumbersome and imprecise than the German and English Wikipedias, stated that it often lacked reliable sources, including much unreferenced data, and found it to be too dependent on online references.
According to a 2013 Oxford University study, five of the ten most disputed pages on the Spanish Wikipedia were football (soccer) clubs, including Club América, FC Barcelona, Athletic Bilbao, Alianza Lima, and Newell's Old Boys.
In a study published in 2017, seventy-seven university students, most with Catalan and/or Spanish as their native languages, made contributions to the English, Spanish and Catalan Wikipedias as part of assessed work and responded to questionaries. The students preferred the English Wikipedia when looking for general information despite the fact that English was the language they reported being less proficient at: "In many of the open comments on the differences between language editions, the students suggested that the English version was better, more complete or more reliable." Specifically, the participants were asked the following question: "If an article is available in Catalan, Spanish and English, which version are you most likely to read first?" The majority responded that they read articles in English first. The researchers wrote that "the English version was seen by many of the students as the main reference page, and they stated that they used it ‘by default’," and highlighted that "the students responded to this question after having written a Wikipedia article and undergoing the process of publishing it (and thus of the strict peer review curation of the Wikipedia community of volunteers)."

### Rebelión.org

During Wikimania 2009, free-software activist Richard Stallman criticized the Spanish Wikipedia for restricting links to the Rebelión.org left-wing web site and allegedly banning users who had complained about what had happened. Participants on the Spanish Wikipedia responded that Rebelión.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.

### Pro-Russian disinformation

In April 2022, the European Union's East StratCom Task Force found that four pro-Russian disinformation news outlets (SouthFront, NewsFront, InfoRos and Strategic Culture Foundation) were referenced in 52 articles of the Spanish Wikipedia. This made it the third most affected Wikipedia edition by such disinformation, behind the Russian and Arabic Wikipedias. They wrote:
   On the English version of Wikipedia, there seems to be a consensus that state-sponsored disinformation sites aren't legitimate sources [...]. One can only guess whether other language versions will follow suit, but there is nothing stopping anyone from launching that debate, pointing out the English Wikipedia example as a best practice.

### Political bias

The Spanish Wikipedia has been criticized for offering a whitewashed coverage of left-wing politician Cristina Kirchner while presenting a negative portrayal of her center-right opponent Mauricio Macri. The May 2020 article in La Nación emphasized that, even though Argentine newspaper Clarín had published an article six months prior (November 2019) highlighting these political biases and their objectionable nature, the Spanish Wikipedia had not corrected the reported problems, no matter how much it says of itself that incorrect information "is quickly corrected".
In March 2021, Argentine historian Luis Alberto Romero [es] criticized the Wikimedia Argentina chapter in Clarín. He described how hundreds of articles on the history of Argentina were manipulated "with the classic taste of the K narrative" in the Spanish Wikipedia. He blamed those on the top of the Spanish Wikipedia hierarchy, who can "accept or reject the collaborations" and who "since 2009 are crowded by a group of Kirschnerist militants".
In June 2022, Venezuelan newspaper El Nacional observed that the Spanish Wikipedia describes the United Socialist Party of Venezuela as "a political party with socialist, anticapitalist, antiimperialist and internationalist ideology, which takes as its principles Simon Bolivar's work, scientific socialism, Christianism and liberation theology." El Nacional then observed that the Spanish Wikipedia article omits that the party's goal has been to turn into the only existing political organization in Venezuela.
In July 2022, an article in Infobae criticized the Spanish Wikipedia for using euphemisms to describe Cuba's political system to avoid a clear characterization as a dictatorship. The author ridicules the Spanish Wikipedia for claiming that Cuba is "similar to other states with parliamentary forms of government" and that its National Assembly "consists of representatives that are elected by universal, free, direct and secret vote" by Cubans every five years.
In September 2022, a manifesto signed by Juan Carlos Girauta, Álvaro Vargas Llosa, Cayetana Álvarez de Toledo, Joaquín Leguina, Albert Rivera, Daniel Lacalle, Lucía Etxebarría, Félix de Azúa, Francisco Sosa Wagner, Cristina Ayala, Miriam Tey and Toni Cantó among others was published denouncing political bias on the Spanish Wikipedia. They also denounced that the Spanish Wikipedia refuses to correct false claims, including some that are damaging to living persons.
In the view of Florencia Claes, the president of Spain's Wikimedia chapter, "the Spanish Wikipedia is markedly right-wing".
