The call invites the public to create and distribute Wikipedia articles and upload photos to Wikimedia Commons on the topic of Czechoslovakia.
It doesn’t have to be only about historical events or personalities, you can also write about everyday objects, contemporary TV shows or culture.
This year, the challenge has a rich accompanying programme. We are already giving you a small taste.
You can find out more now on the challenge website, where you can also register for the events one by one. ceskoslovensko.wikimedia.cz
