“Deep State” comes from the Turkish derin devlet, a clandestine network, including military and intelligence officers, along with civilian allies, whose mission was to protect the secular order established, in 1923, by the father figure of post-Ottoman Turkey, Mustafa Kemal Atatürk. It was behind at least four coups, and it surveilled and murdered reporters, dissidents, Communists, Kurds, and Islamists.
