Stell dir eine Welt vor, in der jeder einzelne Mensch frei an der Summe allen Wissens teilhaben kann.
The non-profit Wikimedia Foundation provides the essential infrastructure for free knowledge. We host Wikipedia, the free online encyclopedia, created and edited by volunteers around the world, as well as many other vital community projects. We welcome anyone who shares our vision to join us in collecting and sharing knowledge that fully represents human diversity.
Research
We conduct our own research and partner with researchers worldwide to address change in society and technology.
Technology
From site reliability to machine learning, our open-source technology makes Wikipedia faster, more reliable, and more accessible worldwide.
Advocacy
We fight to protect everyone’s right to access free and open knowledge.
Projects —
Collaborative projects are the core of the Wikimedia movement.
Our volunteers build tools, share photos, write articles, and are working to connect all the knowledge that exists.
PARTICIPATE — Profiles
Wikimedians are heroes of free knowledge.
Throughout history, knowledge has been controlled by a powerful few. Wikipedia needs knowledge from all languages and cultures. The internet has become the default for accessing information—women, people of color, and the global south remain underrepresented. We invite you to help correct history.

KEY INFORMATION —
Things to know
Wikimedia projects belong to everyone
You made it. It is yours to use. All text on Wikimedia sites is available as Creative Commons material. That means you can use it, re-write it, or share it. Just do not write you own bio, or copy/paste it in your homework.
Your data belongs to you
We do not sell or share your email address or any of your personal information with third parties. More information about our privacy practices are available at the Wikimedia Foundation privacy policy, donor privacy policy, and requests for user information procedures and guidelines.
People like you keep Wikipedia accurate
Wikipedia articles are collaboratively created and edited by a community of volunteers using reliable sources. Readers verify the facts. No single person or company owns a Wikipedia article. We cannot change a Wikipedia article about you, but others can help.
Not all wikis are Wikimedia
The word “wiki” refers to a website built using collaborative editing software. Hundreds of organizations and projects with no affiliation with Wikipedia or the Wikimedia Foundation also use the term, including wikiHow and WikiEducator.
Wikimedia has nothing to do with Wikileaks and never did. Although both use the term “wiki” in their name, they have always been completely separate and unaffiliated.
Help us unlock the world’s knowledge.
As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.
