Where Does the Term "Deep State" Come From?

"The origins of the term Deep State are from the secretive Turkish network known as derin devlet. This group was founded in 1923 by Mustafa Kemal Atatürk with the purpose of undertaking clandestine acts to preserve the current governmental structure. These acts included coups and private assassinations of figures who were seen as hostile to the establishment; they were particularly targeted toward the press, communists, Kurds, and other dissenters."
