Wikimedia chapters are national or sub-national not-for-profit organisations created to promote the interests of Wikimedia projects locally. Chapters are legally independent of the Wikimedia Foundation, entering into a "Chapters Agreement" with the Foundation following acceptance by the Affiliations Committee (formerly known as "Chapters Committee"), and have no control over Foundation websites. They organise regional conferences, outreach and global events such as Wikimania. As of January 2015 there were 41 recognised Wikimedia chapters.
