The Croatian Wikipedia (Croatian: Wikipedija na hrvatskom jeziku) is the Croatian version of Wikipedia, the free encyclopedia, started on February 16, 2003. This version has more than 140,000 articles as of August 2013[update], making it the 39th largest edition of Wikipedia.
As of September 2013[update], the Croatian Wikipedia had more than 116,000 registered user accounts, out of which 466 were active (defined as having performed an action on Wikipedia in the last 30 days) and 27 were administrators. Throughout the first half of 2013, fewer than two dozen editors made more than 100 edits a month; around 150 made more than 5 edits a month. As of September 2013[update], there were 430 featured articles (Croatian: Izabrani članci).
In September 2013 complaints about right-wing bias of administrators and editors on the Croatian Wikipedia arose. Those complaints were already present, but they started receiving media attention after the launch of a Facebook page titled Razotkrivanje sramotne hr.wikipedije (Exposing the shameful Croatian Wikipedia) whose creators warned the media about the bias. Notable examples of bias include historical revisionism such as watering-down and even denial of the crimes committed by the Ustaše regime, while equating anti-fascism with forms of totalitarianism. Other examples include the bias against Serbs of Croatia and the LGBT population. Editors who tried to remove the bias were reportedly being harassed by administrators and quickly received permanent blocks under some pretext. The issue was reported by Croatia's daily Jutarnji list and even made its print edition's front page on 11 September 2013.
On 13 September 2013 Croatia's Minister of Science, Education and Sports, Željko Jovanović, called for pupils and students in Croatia to avoid using the Croatian Wikipedia. In an interview given to Novi list, Jovanović said that "the idea of openness and relevance as a knowledge source that Wikipedia could and should represent has been completely discredited – which, for certain, has never been the goal of Wikipedia's creators nor the huge number of people around the world who share their knowledge and time using that medium. Croatian pupils and students have been wronged by this, so we have to warn them, unfortunately, that a large part of the content of the Croatian version of Wikipedia is not only dubious but also [contains] obvious forgeries, and therefore we invite them to use more reliable sources of information, which include Wikipedia in English and in other major languages of the world." Jovanović has also commented on the Croatian Wikipedia editors – calling them a "minority group that has usurped the right to edit the Croatian-language Wikipedia".
In an interview given to Index.hr, Robert Kurelić, a professor of history at the Juraj Dobrila University of Pula, has commented that "the Croatian Wikipedia is only a tool used by its administrators to promote their own political agendas, giving false and distorted facts". As two particularly prominent examples he listed the Croatian Wikipedia's coverage of the term Istrijanstvo (Istrianregionalism), defined as a "movement fabricated to reduce the number of Croats", and antifašizam (anti-fascism), which according to him is defined as the opposite of what it really means. Kurelić further advised "that it would be good if a larger number of people got engaged and started writing on Wikipedia", because "administrators want to exploit high-school and university students, the most common users of Wikipedia, to change their opinions and attitudes, which presents a serious issue".
