The Imam's Army is a book by Turkish journalist Ahmet Şık on the life and work of Fethullah Gülen and his Gülen movement. Şık was detained in March 2011, before the book was published, and the draft book was seized by the government and banned, claiming it was an "illegal organizational document" of the secret organization Ergenekon. Şık was detained pending trial, being eventually released pending trial in March 2012. In the interim, in an act of anti-censorship defiance, a version of the book was released in November 2011 under the name 000Kitap (000Book), edited by 125 journalists, activists and academics, and published by Postacı Publishing House.

Ahmet Şık is a Turkish investigative journalist, the author of several books, a trade unionist, and member of Parliament in Turkey. His book, The Imam's Army, investigating the controversial Gülen movement of the Islamic preacher Fethullah Gülen, led to his detention for a year in 2011–2012 and the book's being seized and banned. He was under indictment in the OdaTV case of the Ergenekon trials; his cause has been taken up by English PEN, an association of writers fighting for freedom of expression. In 2016, the prosecutor in this case requested Şık's acquittal. On 29 December 2016, Şık was taken into custody once again on charges of "propaganda of terrorist organisations", with reference to 11 tweets that he had published. The following day, an Istanbul judge ordered Ahmet's arrest. According to lawyers, Şık was denied access to legal advice, held in solitary confinement, and not given drinking water for three days. He ran as an HDP candidate in 2018 Turkish elections and got elected from Istanbul's second electoral district. In 2020, he resigned from HDP, citing political differences and after sitting as an independent for a year, he joined the Workers' Party of Turkey.
