In 1997 the Turkish military forced the Islamist-led coalition government of Prime Minister Necmettin Erbakan from office through a memorandum of demands rather than an armed takeover, an episode known as the postmodern coup; Erbakan resigned on June 18, 1997 and a new government took office on June 30. Erbakan's Welfare Party had led a coalition since 1996, alarming the strongly secularist military establishment. At a marathon National Security Council meeting on February 28, 1997, the generals issued a series of ultimatums to protect secularism, backed by shows of force such as tanks in an Ankara district.
Under sustained pressure, Erbakan signed the decrees and then resigned on June 18, 1997. Rather than appoint his coalition partner, the president tasked Mesut Yilmaz with forming a new government, which took office on June 30, 1997. No one was physically harmed and the constitution was not suspended.
The dataset dates this June 30, 1997 and codes the fate as not physically harmed.

The 1997 Turkish military memorandum, also called the postmodern coup, refers to decisions issued by the military leadership at a National Security Council meeting on 28 February 1997 which resulted in the resignation of Islamist prime minister Necmettin Erbakan of the Welfare Party and the end of his coalition government, and as the government was forced out without dissolving parliament or suspending the constitution the event has been labelled a postmodern coup.

Erbakan was forced to resign as a result of the military memorandum, and although the coalition parties declared they should form the new government under Tansu Ciller, President Demirel appointed ANAP leader Mesut Yilmaz to form the new government, who formed a new coalition on 30 June 1997.

Under the pressure of the process, Prime Minister Erbakan resigned before the end of his term, submitting his resignation to Demirel on June 18, 1997, and although the government protocol stipulated that Tansu Ciller should be given the task, the president assigned it to Mesut Yilmaz.
SOURCE REVIEWEDDaily Sabah, Feb 28 1997 the post-modern coup of Turkiyeopen source ↗
On February 28, 1997 the military-dominated National Security Council issued a series of recommendations or ultimatums to the government on actions needed to protect secularism, and enough members of the junior coalition partner defected to cause the Erbakan government to fall and force Erbakan to step down, in what was popularly dubbed a postmodern coup.
Coding note and dataset examination: the dataset labels this a military coup with a not-physically-harmed fate, dated June 30, 1997. This is the famous postmodern coup: the military forced the elected Islamist-led government out through a memorandum of ultimatums (the February 28 process) and sustained pressure, rather than by tanks seizing the state, and notably without dissolving parliament or suspending the constitution, which is why it is called postmodern. Date reconciliation: the triggering memorandum was February 28, 1997; Erbakan resigned June 18, 1997; and the successor Yilmaz government took office June 30, 1997, which is the date the dataset uses to mark the completed change of government, and the full sequence is recorded. Who is coded deposed: Prime Minister Necmettin Erbakan, not physically harmed, matching the dataset. Contested subject handled neutrally: the military and its supporters framed the intervention as a defense of secularism against an Islamist threat, while critics, and later a Turkish court, characterized it as an undemocratic ouster of an elected government; both framings are recorded rather than adjudicated, and the later prosecution of officers is noted as documented later context. Neutrality maintained on a contested subject.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
