Wikimania is the Wikimedia movement's annual conference, organized by the community of contributors and hosted by the Wikimedia Foundation. Topics of presentations and discussions include Wikimedia projects such as Wikipedia, other wikis, open-source software, free knowledge and free content, and social and technical aspects related to these topics.
Since 2011, the winner of the Wikimedian of the Year award (known as the "Wikipedian of the Year" until 2017) has been announced at Wikimania.
HistoryLayer draws the world as it was in any year from 123,000 BCE to
2026. Move the slider and the borders redraw for that year; the map
carries 23,890 events, 12,790 people, 837 wars and 13,183 cities, each
one readable in place. Signing in is optional and lets you keep what
you find.
