The Turkish Armed Forces executed a "coup by memorandum", forcing the resignation of Prime Minister Süleyman Demirel.

Turkish Armed Forces
The Turkish Armed Forces are the military forces of the Republic of Turkey. The TAF consist of the Land Forces, the Naval Forces and the Air Forces. The Chief of the General Staff is the Commander of the Armed Forces. In wartime, the Chief of the General Staff acts as the Commander-in-Chief on behalf of the President, who represents the Supreme Military Command of the TAF on behalf of the Grand National Assembly of Turkey. Coordinating the military relations of the TAF with other NATO member states and friendly states is the responsibility of the General Staff.
1971 Turkish military memorandum
The 1971 Turkish military memorandum, issued on 12 March that year, was the second military intervention to take place in the Republic of Turkey, coming 11 years after its 1960 predecessor. It is known as the "coup by memorandum", which the military delivered in lieu of sending out tanks, as it had done previously. The event came amid worsening domestic strife, but ultimately did little to halt this phenomenon.
