History.
Swedish Wikipedia was launched by Jim Wales on 23 May 2001 as Wikipedia's 4th language version. The "Phase I" UseModWiki software for "sv.wikipedia.com" was translated by Linus Tolke and the "Phase III" MediaWiki was translated by Dan Koehl together with Johan Dahlin and Max Walter. The latter, contemporary PHP-engined MediaWiki Swedish interface premiered on "sv.wikipedia.org" 1 December 2002, becoming the foundation for later updates. Dan Koehl was appointed Swedish Wikipedia's first ". He set up the early community features such as ", maintenance functions such as sabotage deterrence, pioneered much of its fundamental corpus of articles, and called to the first "Tinget". This wiki "thing" of 24 November 2002 became the first instance akin to an arbitration committee on any Wikipedia language version, effectively making Swedish Wikipedia the first decentralised franchise while the rest of Wikipedia was still under Jim Wales' direct personal supervision.
The first years, Swedish Wikipedia functioned as a small, foreign-franchised competitor to the independently Swedish UseModWiki Susning.nu created by Lars Aronsson in 2001, inspired by English Wikipedia. However, the founder's decision to allow advertisement on the website from 20 November 2002 led Dan Koehl to switch over to Swedish Wikipedia, with several prolific contributors gradually following suit. Although Susning.nu became the world's second largest wiki 28 May 2003, in April 2004, its editing features were closed down to all but a handful of users, which further increased the flow to Swedish Wikipedia. On 14 January 2005, Wikipedia's article count surpassed that of Susning.nu. Susning.nu was shut down entirely in August 2009.
In March 2006, the Swedish newspaper "Svenska Dagbladet" published a comparative evaluation of Swedish Wikipedia, Susning.nu and the online version of Nationalencyklopedin. The evaluation was done by giving a selection of articles to independent subject matter experts for grading. While Nationalencyklopedin came out on top with respect to factuality and neutrality, Swedish Wikipedia received a good overall grade and came out on top with respect to being up to date and having a broad coverage, also including popular culture subjects.
On 27 September 2012 it reached 500,000 articles. On 15 June 2013 it reached 1,000,000 articles and rose from 8th to 5th place. This meant that during 2012 and 2013 the number of articles on Swedish Wikipedia more than doubled. This is in large part due to a community project where bots were used in producing articles for all existing species of plants and animals. When finished, this project alone created more than a million articles, most short and sourced through available online databases on the subject. In 2014 about half of its articles were created by a single bot. During 2015 and 2016, Lsjbot wrote more than 1 million geographical articles, increasing the number of articles to nearly 3.8 million articles by November 2016 when it stopped. Meanwhile, Swedish became the second largest Wikipedia, due to the creation of the geographical articles. Since then about 600,000 of these geographical articles have been deleted due to various deficiencies (e.g. notability, documentation), and the total article count has decreased from nearly 3.8 million in November 2016 to less than 3.5 million articles in December 2020. This continuous fall in articles has continued into 2021, as due to the ongoing deletions of robot-made articles the number of articles has further decreased to below 3.4 million articles as of 3 March 2021, while in 17 March 2021 the number of articles further fell below 3.3 million articles. 
On a typical day, Swedish Wikipedia at average deletes 400 to 3,000 Lsjbot-made articles. However, periodically the deletions may be below 400 articles per day, but in some days even 5,000 to 6,000 articles have been deleted. Since March 2021, the pace of deletions has increased again greatly, reaching above 4,000 articles almost every day. However, many quality indicators have improved significantly, like the article depth which has doubled from 5 in November 2016 to 10. The article depth is an approximate number, as for example, in 20 March 2021 it was 9.95, but List of Wikipedias shows 10. 
Topics.
In 2019 the Swedish Wikipedia had 354 thousand unique categories. The average article in this language version had 5 categories and ratio of unique categories to articles was 0.094. The categories with the largest number of articles in 2019 were "Life" (30%) and "Geography" (24%). In the Swedish Wikipedia, articles related to Geography and Life had the highest average quality. Content about Health was read more often and articles in the Events category had the highest average author interest.
Verifiability.
In March 2020 the Swedish Wikipedia contained 20.1 million references, wherein 4.31% of them had the DOI and 0.72% of references contained the ISBN.
