The Wikimedia movement is the global community of contributors to the Wikimedia projects, including Wikipedia.[1][2] This community directly builds and administers these projects[3] with the commitment of achieving this using open standards and software.[4]
First created around and by Wikipedia's community of volunteer editors (Wikipedians), it has since expanded to other projects like Wikimedia Commons and Wikidata and volunteer software engineers and developers contributing to the software used to power Wikimedia, MediaWiki.
