Ahmet Talât Aydemir (1917 in Söğüt – 5 July 1964 in Altındağ) was a Turkish officer who led two unsuccessful military coup attempts on February 22, 1962 and May 20, 1963 and was executed for his part in them.
Graduating in August 1954, he was stationed in Ankara and was soon appointed to the Planning Branch of the General Staff Logistics Directorate.
[4] Between 1956 and 1959, Aydemir was a member of the group of officers conspiring to stage a coup against Turkey’s Democratic Party government.
[9]: 15 The indecisive outcome of the first post-coup elections on October 15, 1961 led to increased discontent within the army and a group of officers organised what they called the Armed Forces Union (Silahlı Kuvvetler Birliği).
The government led by İsmet İnönü tried to dissuade these officers from taking action, but when it was clear their advice was being ignored, they prepared to assign the ringleaders, including Aydemir, to new posts far from the capital.
Knowing that Aydemir and his associates were planning a coup, his relative the politician Ekrem Alican offered to try and dissuade him, but his effort was unsuccessful.
[10] To pre-empt the dispersal of his co-conspirators, Aydemir organized a coup attempt on February 22, 1962, with the participation of some of the military units in Ankara.
However most of the army sided with İsmet İnönü, compelling Aydemir to surrender in return for an assurance that the leaders of the coup would not be tried or punished.
On May 20, 1963, he mounted his second coup attempt with the participation of the Military Academy, on the grounds that the reforms envisaged in the Constitution were not being implemented.
After the trial, he was sentenced to death along with Cavalry Major Fethi Gürcan on September 5, 1963, for "attempting to amend and falsify the constitution".
