Wikipedia:25th anniversary

A quarter century of free knowledge!

On 15 January 2026, Wikipedia celebrated the 25th anniversary of its founding in 2001. The English edition has grown to include more than 7 million articles—all written collaboratively by volunteers.

Wikipedia started as an ambitious idea to create a free encyclopedia, written by volunteers, for everyone in the world. It seemed impossible. Over 25 years, Wikipedia has become the largest collection of open knowledge in history. How did it happen? (1 min 30 s)

25 years of Wikipedia: How a single free encyclopedia can do the unthinkable

The biggest encyclopedia ever, with over 7 million articles and counting has turned a quarter century years old, and many search engines copy the info. An encyclopedia that takes over the world, an encyclopedia to make humans smarter, an encyclopedia that refuses to quit, an encyclopedia that translates into 300+ languages, an encyclopedia that will keep developing for eternity, an encyclopedia for all purposes, an encyclopedia that freshens everyone's mind, an encyclopedia that can be shared to anyone's friend of his / her and an encyclopedia that stays forever with you. 25 years of Wikipedia, the most powerful encyclopedia to make humans feel like a better person. Have a positively good birthday, I guess.

有史以來最大嘅百科全書，有超過700萬篇文章，而且仲計緊，已經過咗四分一世紀，而且好多搜尋引擎都會複製呢啲資料。一本接管世界嘅百科全書，一本令人類更聰明嘅百科全書，一本拒絕放棄嘅百科全書，一本可以翻譯成300多種語言嘅百科全書，一本會永遠發展嘅百科全書，一本可以用嚟做所有用途嘅百科全書，一本可以令大家心靈清新嘅百科全書，一本可以分享畀任何人嘅朋友嘅百科全書，同埋一本永遠陪伴你嘅百科全書。 25年嘅維基百科，係最強大嘅百科全書，令人類覺得自己係一個更好嘅人。我估祝你生日快樂。

Although knowledge is human, but knowledge is for the best for expanding into a better person.

雖然知識係人，但係知識係為咗擴大成為一個更好嘅人而最好。

Happy Birthday Wikipedia

Honestly this site saved my assignment multiple times, so thanks.

Happy somewhat-belated Birthday, Wikipedia!!!

I've been reading and writing (mostly reading, though) on here since I was... what, elevn years old? God, life has changed so much since then. Wikipedia has pushed my interests in history, science, and politics so much farther than I ever imagined, and I'm honored to say that Wikipedia is the reason I'm stuying history professionally. From the bottom of my heart, thank you to all my fellow Wikipedians, as well as everyone working at the Wikimedia Foundation, for making this nerd even just a little bit smarter. i honestly got alot of answers to questions from this dear website

Happy birthday!!
