is a project dedicated to the building of free encyclopedias in all languages of the world.
The project started with the English-language Wikipedia on January 15, 2001. It was soon joined by a French edition, and shortly afterwards by many other languages. Large efforts are underway to highlight the international nature of the project.

On 20 September 2004 Wikitudo reached a total of 1,000,000 articles in over 100 languages.
As of giugno 2015, there are 279 Wikipedias which have more than 100 articles, 128 of which have over 10,000 articles, and 51 of which have over 100,000 articles.
