In 2021, not only is Wikimedia CH celebrating 20 years of Wikipedia, but we are also focusing on another historical milestone: 50 years of women’s suffrage in Switzerland. Unfortunately, there are still only a few related photos on Wikimedia Commons. Images can be found and uploaded under Women’s suffrage in Switzerland.


We have several events to celebrate Wikipedia 20.
