Şevket Süreyya Aydemir (1897 in Edirne – 25 March 1976 in Ankara) was a Turkish writer, intellectual, economist, historian, and one of the founders and a key theorist of Kadro ("Cadre"), an influential policy journal published in Turkey from 1932 to 1934. He was educated and became familiar with Marxism at Moscow University where he studied economics, and worked as a teacher in Georgia, Azerbaijan, and Russia. He was a member of the Communist Party of the Soviet Union and the Communist Party of Turkey, and attended a Soviet-sponsored Congress for the Peoples of the East in Baku on the Turkish party's behalf.
Upon his return to Turkey from the Soviet Union, he wrote for Aydınlık magazine. The magazine was shut down in 1925 for political reasons, and he was sentenced to 10 years in prison by the Ankara Independence Court for the views he had expounded in the magazine. He was released after a year and a half. He was tried again in 1927 but this time was acquitted.
Sobered by his prison experience, Aydemir mixed his Marxist–Leninist leanings with more mainstream nationalist Turkish ideology to create the basis for the Kadro theory. Aydemir argued that Turkey–economically subjugated itself at independence–would lead a new world order where former colonies and economically subjugated states would rise up and overcome the hegemony of the industrialized world. This is where the Kadro would come in:
"The ideal [of a completely state orientated economy] can only be achieved under the guidance, as well as the administration of, the devoted, disciplined cadre, which is indifferent to class or individual interests. Such a cadre, which has discerned the principles of the reform and adapted them as moral values, and a reform generation, are needed for the sake of the success of the reform"
Aydemir was a prolific writer. His most famous work was İnkılap ve Kadro ("Revolution and the Cadre"), published in 1932, where he outlined his theory of political economy presented in the Kadro journal. He published his memoirs, Suyu Arayan Adam ("The Man Searching for Water") in 1959. Between 1963 and 1965, he published Tek Adam ("The Single Man"), a three volume tome on Mustafa Kemal Atatürk. He also published a biography of İsmet İnönü titled Ikinci Adam ("The Second Man").
