From 29 April 2017 to 15 January 2020, the online encyclopedia Wikipedia was blocked in Turkey. On 29 April 2017, Turkish authorities blocked online access to all its language editions throughout the country.[1][2] The restrictions were imposed by Turkish Law No. 5651,[3] due to the English version's article on state-sponsored terrorism (in the version of 29 April 2017), where Turkey was described as a sponsor country for the Islamic State and Al-Qaeda. The ICTA (Information and Communication Technologies Authority) released a statement on its website that after technical analysis and legal consideration based on the Law Nr. 5651, measures have been taken for the website.[4] Turkish courts viewed the article as a public manipulation of mass media.[5] Requests by the Turkish Information and Communication Technologies Authority to edit several articles to comply with Turkish law were not acted on.
Wikimedia Foundation Executive Director Katherine Maher said in May 2018 that the Foundation was "not sure why there is still a ban".[6] In March 2018, Wikipedia's Facebook page started the "We Miss Turkey" (Turkish: Özledik) campaign and replaced the black censor bar over the Wikipedia logo with a red one. It also had an accompanying hashtag of the same name.[7]
On 26 December 2019, the Constitutional Court of Turkey ruled that the block of Wikipedia violated human rights and ordered it to be lifted.[8] On 15 January 2020, the block of Wikipedia in Turkey was lifted.[9][10][11]
