Wikimedia Deutschland feiert 20 Jahre Wikipedia

Zum Geburtstag

We set knowledge free

Wikimedia Deutschland is part of a worldwide movement advocating Free Knowledge. As a non-profit organization, we support Wikipedia and its sister projects by promoting volunteers, developing free software and by standing up at all levels of society for access to knowledge and education as a human right .

Vision, Mission & Conviction


Imagine a world…

…where everybody can freely participate in, use and increase the sum of all human knowledge. This is our vision of Free Knowledge.


Support digital volunteering

We are committed to equal opportunities in access to knowledge and education, and we support the many thousands of volunteers who share their knowledge with everyone every day, for example in Wikipedia.


Free Knowledge brings about change

Access to knowledge and education is a basic human right. Free Knowledge leads to a cosmopolitan, well-informed and fairer society.

Your donation for Wikipedia and Free Knowledge

As a non-profit association, Wikimedia Deutschland is financed primarily by voluntary donations in addition to membership fees. This financial support ensures the independence of Wikipedia and other free knowledge projects. Support us with a donation – because together we can achieve more!
