Turkish marshal and statesman who played a leading role in the establishment of the Turkish Republic.

Çakmak was educated at Turkish military colleges and was commissioned as a lieutenant in 1895. He fought in the Balkan Wars (1912–13) as commander of a division at Vardar, and in World War I he successively commanded the Ottoman troops at the Dardanelles, in the Caucasus, and in Syria. He became a general in 1914 and was appointed chief of the Turkish general staff four years later.

Appointed minister of war in the sultan's government in Constantinople (1920), he resigned his post to join the resistance of Mustafa Kemal (later Atatürk) to the Allied occupation of Anatolia. Çakmak was made prime minister and minister of war in the government of the Grand National Assembly in Ankara. Promoted to the rank of full general in April 1921, he resigned his premiership in 1922 and became deputy to İsmet İnönü, then chief of staff. After the Turkish War of Independence (1920–21), he was appointed chief of staff of the Turkish Army, a post he held until 1944.

In 1946, being opposed to the one-party rule of İnönü, then the president of Turkey, and to the extreme secularism of the Republican People's Party (RPP), Çakmak entered the elections as an independent on the ticket of the Democrat Party (DP), the newly formed opposition to the RPP. He was elected to the assembly by an overwhelming majority, but, dissatisfied with the DP, he accepted in 1948 the honorary chairmanship of the conservative National Party (Millet Partisi).
