On March 12, 1971 the Turkish Armed Forces forced Prime Minister Suleyman Demirel to resign through a written ultimatum, the coup by memorandum, the second military intervention in the republic's history and one delivered without tanks in the streets. Turkey had descended into near chaos by early 1971: economic recession, paralyzing strikes, university shutdowns, and escalating political violence between the radical left and the far-right Grey Wolves, while Demirel's centre-right Justice Party government, weakened by defections that cost it its majority, appeared unable to restore order or pass reforms. On March 12 the Chief of the General Staff, Memduh Tagmac, handed Demirel a memorandum demanding a strong, credible, above-party government to end the anarchy and implement reforms in the spirit of Ataturk, warning that otherwise the army would take power directly.
After a three-hour cabinet meeting, Demirel resigned. The commanders, wary of the Greek junta's example, chose to rule from behind the scenes through a technocratic above-party government under Nihat Erim, giving directives while parliament formally continued. The intervention curtailed the liberal 1961 constitution but did little to stem the violence it cited.

The 1971 Turkish military memorandum, issued on 12 March, was the second military intervention in the Republic of Turkey, known as the coup by memorandum, which the military delivered in lieu of sending out tanks; on 12 March the Chief of the General Staff Memduh Tagmac handed Prime Minister Demirel a memorandum amounting to an ultimatum, demanding a strong government to neutralise the anarchical situation, and Demirel resigned after a three-hour meeting with his cabinet.

The memorandum demanded the formation, within democratic principles, of a strong and credible government to neutralise the current anarchical situation and implement reformist laws, warning that if the demands were not met the army would exercise its constitutional duty and take over power itself; the commanders, reluctant to rule directly and deterred by the problems facing the Greek junta, chose Nihat Erim on 19 March to lead an above-party technocratic government while giving directives from behind the scenes.

The intervention was effectively a coup, unique in that instead of using tanks and troops the military issued a memorandum demanding the government restore order and implement reforms, and left with no other option Demirel's government complied and resigned, after which a technocrat-led government was appointed and the episode gave rise to a two-headed power structure in which a military-guided state power overshadowed elected governments.

An immediate spur for the intervention was the kidnapping of four American servicemen by leftist militants on March 4, 1971, eight days before the memorandum, amid a period in which more workdays were lost to strikes between 1 January and 12 March 1971 than in any prior year and universities had ceased to function.

Editorial Note
Coding note: the dataset labels this a military coup though it took the form of a written ultimatum rather than an armed seizure, hence its nickname the coup by memorandum; Demirel was not physically harmed and resigned, matching the dataset fate. Distinct event: this is the second of Turkey's military interventions, separate from the 1960 coup (a distinct earlier dataset event); it curtailed the liberal 1961 constitution and installed a behind-the-scenes military tutelage. Arc forward: Demirel returned as prime minister later in the 1970s, and Turkey experienced a further, harder coup in September 1980, both separate later events.
