text: The coup was planned to take place on 11 July 1980, but was postponed after a motion to put Demirel's government to a vote of confidence was rejected on 2 July. At the Supreme Military Council meeting () on 26 August, a second date was proposed: 12 September.
  On 7 September 1980, Evren and the four service commanders decided that they would overthrow the civilian government. On 12 September, the National Security Council (, MGK), headed by Evren declared coup d'état on the national channel. The MGK then extended martial law throughout the country, abolished the Parliament and the government, suspended the Constitution and banned all political parties and trade unions. They invoked the Kemalist tradition of state secularism and in the unity of the nation, which had already justified the precedent coups, and presented themselves as opposed to communism, fascism, separatism and religious sectarianism.
  The nation learned of the coup at 4:30 AM UTC+3 on the state radio address announcing that the parliament had been dismissed and that the country was under the control of the Turkish Armed Forces. According to the Armed Forces broadcast, the coup was needed to save the Turkish Republic from political fragmentation, violence and the economic collapse that was created by political mismanagement. Kenan Evren was appointed head of the National Security Council ().
