In software engineering, a project fork occurs when developers take a copy of source code from one software package and start independent development on it, creating a distinct piece of software. but instead launched in March 2007 with an emphasis on original content. The project's aim was to improve on the Wikipedia model by providing increased reliability.

Founder viewpoints

Sanger said in a 17 October 2006 press release that Citizendium "will soon attempt to unseat Wikipedia as the go-to destination for general information online".
[Larry Sanger]
, Citizendium, 17 October 2006. In August 2007, he captioned its pages: "The world needs a more credible free encyclopedia."
The project began its pilot phase in October and November 2006.
On 18 January 2007, a change of plans was announced. Sanger announced on the CZ (Citizendium) mailing list that only articles marked "CZ Live", those which have been or will soon be worked on by Citizendium contributors, would remain on the site, and all other articles forked from Wikipedia would be deleted. Not all Citizendium contributors were supportive of this change, but Sanger emphasized that this deletion was "an experiment" and a new set of Wikipedia articles could be uploaded if the experiment were deemed unsuccessful.

Planning for succession of editor-in-chief
In May 2009, Sanger reduced his direct activity at Citizendium, and, in a message on 30 July 2009, he reminded those on the Citizendium-l mailing list of his previously declared intention not to serve as editor-in-chief for more than two or three years after the start of the project. Sanger has reiterated his call for the Citizendium community to prepare an orderly process for choosing a new editor-in-chief. Sanger said that he was spending more time on his WatchKnow project, partly because he needs to earn an income—he said the "Citizendium project doesn't earn me a dime"—and partly because the Citizendium community had demonstrated that it could function effectively without his close, daily involvement, and because "there are squeakier wheels in my life just now". He added that stepping aside may "precipitate something of a constitutional crisis, considering that we
itizendiumnever adopted a proper charter". Citizendium finally ratified its charter in September 2010. On 22 September 2010, Sanger stepped down as editor-in-chief, but said he would continue to support the project.

web forum members, Sanger said that a complete fork at launch was not a "foregone conclusion". On 18 January 2007, Sanger announced that the pilot would, as an experiment, only carry articles that had been, or would soon be, worked on by Citizendium contributors, instead of a complete set of Wikipedia articles. He stated that the experiment "represents a reconception of our project's basic aim".
No announcement was made on Citizendium editions in languages other than English, but Sanger stated that they may be forthcoming after the English-language version was established and successfully working. In a review of

'', Sanger comments ironically on Keen's favorable treatment of Citizendium: "The first example of a 'solution' he offers is the Citizendium, or the Citizens' Compendium, which I like to describe briefly as Wikipedia with editors and real names. But how can Citizendium be a solution to the problems he raises, if it has experts working without pay, and the result is free? If it succeeds, won't it contribute to the decline of reference publishing?"
Project goal
The stated aim of the project is to create a "new compendium of knowledge" based on the contributions of "intellectuals," defined as "educated, thinking people who read about science or ideas regularly."

Sanger stated that editors would ''not'' have pre-approval rights over edits by ordinary authors, though editors would have somewhat undefined authority over articles that fall within their specific area of expertise.

"Citizendium launch plan as of 26 September"
, Citizendium-l mail list, 27 September 2006. However, on 2 October 2006, Sanger released a pilot project announcement that envisioned a fully functioning wiki within "one to two months."
In an apparent attempt to quicken the pace of the project, on 2 October 2006, Citizendium web forum moderator Peter Hitchmough suggested what he called an "
alpha test

" of the concept. Hitchmough proposed the forking of a limited number of Wikipedia articles to a site where Citizendium web forum and mailing list members could "rewrite a complete section" of Wikipedia content.
Larry Sanger reacted enthusiastically to the idea and at first suggested his already existing Textop wiki as the site for the alpha test. Sanger later posted that Textop would not be a good choice, but showed continued interest in the proposal. He envisioned a "restricted-access" wiki where the idea could be tried and requested further discussion.
No access to the pilot version of Citizendium, even read-only, was allowed to the general public. Sanger stated: "Only invited people will be able to view and edit the pilot project wiki."
[Larry Sanger]
"Call for applications to participate in the Citizendium Pilot Project"
, Citizendium. Sanger also said that constables for the pilot project will be chosen by the chief constable.
In a press release on 17 October 2006, Sanger announced: "the fledgling Citizendium Foundation will launch a six-week pilot project open to potential contributors by invitation". Several editors and other project leaders were named. It was also announced that the Citizendium Foundation had "started the process of applying for

In a follow-up post to the press release, Sanger said that the initial group allowed access to the pilot would consist of "ten editors, three constables, six authors, and me."
The pilot project began operations on 23 October 2006.

"Developers Wanted: forge.citizendium.org Open"
, Citizendium-l mail list, 23 October 2006. On 8 November, Larry Sanger reported that 263 user names had access to the pilot wiki, 183 articles on the wiki were "live" (meaning "someone is or intends to be working on them") and there were about 300 total edits to the wiki on 7 November.

In a 17 January 2007 post to the Citizendium forum, Sanger stated that "we have had only 10–20 (very) active people out of 500 accounts created." As a result, Sanger decided to delete all articles besides those marked "CZ live" from the pilot project in an attempt to motivate greater participation. On 22 January 2007, Citizendium experimented with a new self-registration procedure: read/write access was granted automatically after creation of the account.
There were a few instances of vandalism after this change, though the vandalism was quickly reverted. On 19 January, Sanger announced the formal organization of Citizendium as a legal non-profit organization.

, Citizendium-l mail list, 22 January 2007. The first act of vandalism was carried out via an account named 'Chris Nguyen', to vandalise three pages including the main one and that of Larry Sanger, apparently before the announcement was made. The account was indefinitely blocked a little over half an hour after the first improper edit. was put on hold while increased protections were being put in place to counter vandalism. The next day, page moves were limited to constables as an additional measure against vandalism. In addition, Sanger continued the process of un-forking the Citizendium from Wikipedia by inviting contributors to delete any Wikipedia content that had changed only superficially since it was imported.
Inauguration
On 25 March 2007, Citizendium ended its pilot phase and went live, into its beta phase, and the site became publicly readable. The launch coincided with a feature-length

The day prior to launch, Sanger released an essay, "Why the Citizendium Will (Probably) Succeed" in which he stated that activity at Citizendium grew from 100 edits a day in the first month to over 500 prior to launch. After the launch, on 27 March 2007, a press release quotes Sanger as saying "You don't have to choose between content and accountability. We have shown that we can create open and credible content. We can, in fact, be open to all sorts of participants, but still hold people to higher standards of content and behavior as a community."

Citizendium Opens its Free Online Encyclopedia Project to the Public
Citizendium, 27 March 2007.
"The modest success of our pilot project shows that there is hope that we can correct exactly the sort of abuses that people demonize Web 2.0 for," said the project's Editor-in-Chief, Wikipedia co-founder Dr. Larry Sanger. "You don't have to choose between content and accountability. We have shown that we can create open and credible content. We can, in fact, be open to all sorts of participants, but still hold people to higher standards of content and behavior as a community."
Sometime after the launch, it was noted that Citizendium's family-friendly policy would mean the project would likely tend to avoid articles on slang terms for sexual activity, and particularly explicit articles on sexual practices.
The Citizendium has a "professionalism" policy for editors, which Sanger said is different from most online communities.
On 29 June 2007, Sanger announced an initiative via the project-wide mailing list that he dubbed "Citizendium 2.0". Characterizing his comments as a "project planning document," Sanger detailed a series of initiatives designed to launch Citizendium into its next phase of development. The document outlined plans for a judicial board, an advisory board, a personnel manager, a new chairman of the editorial council, wider participation in the project by volunteers, a system of subpages for articles, and an expanded article checklist.
Later growth
At the project's first anniversary in September 2007, Citizendium included 3,000
articles written and revised by 2,000 people. A number of media reports appeared in late October and early November 2007 about the anniversary of Citizendium. An article in the ''

'' quoted Larry Sanger predicting strong growth for the project: "At some point, possibly very soon, the Citizendium will grow explosively – say, quadruple the number of its active contributors, or even grow by an order of magnitude. And it will experience that growth over the course of a month or two, and its growth will continue to accelerate from that higher rate."
Citizendium was honored on 5 December 2007, as an award finalist of the Society for New Communications Research. The Society describes itself as a nonprofit global think-tank "dedicated to the advanced study of new communications tools, technologies and emerging modes of communication, and their effect on traditional media, professional communications, business, culture and society." The Society chose Citizendium for an award because it considered it "a leading organization" in these respects.
Decline

Library writer Walt Crawford noted in April 2009 that Citizendium appeared to be in an "extended lull", with a constant rate of creation of new articles at around 13–14 per day and a decline in the number of active authors. In August 2009, Richard Waters wrote in the ''

Recent status
On 2 July 2020, Larry Sanger wrote that he had transferred legal ownership of the Citizendium domain name to Pat Palmer, saying that Citizendium had "stopped being 'my' project a long time ago. But until this morning, I still owned the domain name."
In early 2022, Citizendium upgraded its software to the latest version of MediaWiki. User accounts were not retained and had to be recreated on the new server.
