1997 Turkish military memorandum

The 1997 military memorandum (Turkish: 28 Şubat, "28 February"; also called postmodern darbe, "post-modern coup") in Turkey refers to a memorandum, in which decisions issued by the Turkish military leadership on a National Security Council meeting on 28 February 1997 resulted in the resignation of Islamist prime minister Necmettin Erbakan of the Welfare Party, and the end of his coalition government.

As the government was forced out without dissolving the parliament or suspending the constitution, the event has been famously labelled a "postmodern coup" by the Turkish admiral Salim Dervişoğlu. The process after the coup is alleged to have been organised by the West Working Group, a purported clandestine group within the military.
