Official Timeline of the Wikimedia Foundation
This is the official timeline of the Wikimedia Foundation — which YOU can assist in developing!
Since the Wikimedia Foundation's founding in 2003, the organization has supported the growth of the Wikimedia Movement through a uniquely strong commitment to transparency, collaboration, and empowering people around the world to share their knowledge. In that tradition, we invite you to join us in developing this ever-evolving collection of just some of the expansive story of the Wikimedia Foundation.
This resource is about and from the Wikimedia Foundation specifically. It serves as a supplement to the ongoing efforts by the Wikimedia community to document the Wikimedia Movement's story.

Additional information on this timeline
The Wikimedia Movement Strategy recommends that we manage internal knowledge. It asks us to make the internal knowledge of our movement easy to capture, discover, consume, and adapt by all contributors to facilitate sustainability and resilience, individual and organizational skill development, and growth in an equitable way across all communities. The development of this timeline is an effort to enhance documentation of the Wikimedia Foundation's story. We are providing it as a supplement to the growing array of materials continuously under development which document the 20+ year Wikimedia story.
Given the interconnected nature of the Wikimedia Movement, it is likely that entries on this timeline will appear in other timelines. That is okay! It is important to document all aspects of our collective story. Over the coming months and years, we will continue to look for opportunities to further these documentation efforts, including ways we can use the knowledge gathered via this timeline. If you have ideas for how this timeline could be used or distributed, please let us know.
If you have ideas on what other efforts to help share the Wikimedia Foundation story, please feel free to share them with us via this timeline's talk page or email (answers
