December 6, 2001, marks the date on which the first Basque-language Wikipedia article appeared: Lurra (Earth). The Basque-language main page was then created in November 2003.
Basque Wikipedia published its 100,000th article, on the prohibition of using the Basque language throughout history and titled Euskararen debekua (The banning of Basque) on May 21, 2011; and it reached the 250,000 mark on June 23, 2016. According to a survey in February 2012, Basque Wikipedia had the second greatest number of articles per speaker among all the Wikipedias in different languages. As of 10 am GMT, on December 9, 2016, Basque Wikipedia ranked 31st among the different Wikipedias for the number of articles published (261,726 content pages).
In an August 2007 interview, Jimmy Wales, co-founder of Wikipedia, used the Basque Wikipedia as an example of the rationale for having Wikipedias in smaller languages:
Certainly within Wikipedia right now we are seeing some fairly successful projects in small European languages. You don’t really need a Welsh language Wikipedia, perhaps. The number of people who speak Welsh who don’t also speak English is very small and getting smaller every year. So why do we have a Welsh Wikipedia? Well, people wanted it, so they’re making it. And language preservation is the main motive. It is their mother tongue and they want to keep it alive, keep its literature alive. Certainly some of the larger small languages like Basque and Catalan have very successful projects. I definitely see that preserving parts of your language and culture through collaborative projects makes a lot of sense.
Here at the Center we are proud and honored to be regular users of Basque Wikipedia. Zorionak on your 15th anniversary!
