The Portuguese Wikipedia () is the Portuguese language edition of Wikipedia (written Wikipédia, in Portuguese), the free encyclopedia. It was started on 11 May 2001. In addition to being the sixth most accessed website in the world, Wikipedia is the fifteenth most accessed website in Brazil and the sixth most accessed in Portugal. , it is the largest Wikipedia by article count, containing articles. History The Portuguese Wikipedia was the third edition of Wikipedia to be created, simultaneously with other languages. It started its activities on May 11, 2001, having reached the mark of one hundred thousand articles on January 26, 2006. From late 2004, the edition grew rapidly. In May 2005, it overtook both the Spanish and Italian language Wikipedias. By comparison, in May 2004 it was only the 17th Wikipedia by the number of articles. Portuguese articles can contain variations of writing, as European Portuguese and Brazilian Portuguese have differences in vocabulary and usage. Articles can contain written characteristics of one or the other variant depending on who wrote the article. The Portuguese Wikipedia community decided not to split a separate Brazilian Portuguese version off from the Portuguese Wikipedia. In 2005, a proposal to fork Portuguese Wikipedia and create a Brazilian Portuguese (pt-br) version was voted down by the Wikimedia community. In 2007 another one to create European Portuguese was rejected too by the Wikimedia community. In 2009 another one to create in Brazilian Portuguese was rejected, but this time by language committee, according to new policies to create new Wikipedia editions, with the following explanation: "Brazilian Portuguese is not a separate language.. this is a requirement." Beginning in January 2007, the project experienced a decrease of the share of edits by unregistered users (from around 20 to around 15%) and an increase of the share of such edits being reverted, from about 15% to a peak of 25% in late 2008, which suggests an increase in disruptive editing. In the same month, a JavaScript was added that forced all unregistered users to preview their edit before saving it. In December 2010, the Portuguese Wikipedia overtook the Dutch language Wikipedia in a number of articles, but in the first quarter of 2011, it was surpassed by the Russian and Dutch language Wikipedias, ranking in the tenth position. In April 2016, the project had 1388 active editors who made at least five edits in that month. Characteristics The Portuguese
