History

The Dutch Wikipedia was started on 19 June 2001, and reached 100,000 articles on 14 October 2005. It briefly surpassed the Polish Wikipedia as the sixth-largest edition of Wikipedia, but then fell back to the eighth position. On 1 March 2006, it overtook the Swedish and Italian editions in one day to rise back to the sixth position. The edition's 500,000th article was created on 30 November 2008. In a 2006 Multiscope research study, the Dutch Wikipedia was rated the third-best Dutch-language website, after Google and Gmail, with a score of 8.1.
The Dutch language Wikipedia has the largest ratio of Wikipedia pages per native speaker of all of the top 10 largest Wikipedia editions. Its rate of daily article creations spiked in March 2006, rapidly growing to an average of 1,000 a day in early May 2006. After this number was reached, growth dropped to an average of only about 250 a day, comparable to the averages around December 2005. Since then, there have been more article-creation surges, one of the largest peaking at 2,000 new articles per day in September 2007, but the growth rate has always returned to the lowest average of around 250.
In 2008, Dutch businessman Bob Sijthoff attempted to sue "the Vereniging Wikimedia Nederland" and "the Stichting Wikimedia Nederland" to force the removal of his Dutch Wikipedia article, which he stated contained "false and abusive" information. On 10 December 2008, the court rejected his request. The judge ruled that he had sued the wrong entity and that legal responsibility for the content of the articles would not lie in the Netherlands, but with the American Wikimedia Foundation.

Internet bots

The majority of articles in Dutch Wikipedia were created by internet bots. In October 2011, several bots created 80,000 articles in only 11 days.
The Dutch Wikipedia's one-millionth article was created in December 2011, after another surge of bot activity saw 100,000 added articles in only 10 days. In late March 2013, the Dutch Wikipedia surpassed the French Wikipedia to become the third-largest edition of Wikipedia. In June 2013, it overtook the German Wikipedia to become the second-largest Wikipedia edition.
