Indeed, the period 1930-1944 saw the rise of racism in the Western world based on claims of the being scientific. Therefore, it should not be a surprise if a regime that strove to prove its Westernness by constructing a historiography that aimed to demonstrate in the establishment of the TTAH what sublime racial characteristics the Turkish nation had.

Following the TTAH, the regime’s purpose in creating a Turkish History was embodied in 1932 by the convention of Congress of Turkish History. The delegates at the Congress worked to verify two theses: First that the Turkish Language was the first language on earth and the source of all other languages; and second, that the Turks were the descendants of the Aryan race, who were the creators of civilization. As mentioned above, this second theory was one of the major points Atsız repudiated, yet his repudiation emerged from the understanding of race of the TTAH. Whereas Atsız strengthened his racism by addressing the emphasis from language, which he previously regarded prior to determining a race, to blood; the official theses stressed language in the definition of race.

... The work of Atsız, his studies and theses, especially in his publications, put him in a controversial position with the regime. His first journal in 1931, Atsız Mecmua (Magazine), including articles by famous names such as Fuat Köprülü, Zeki Velidi Togan, Sabahattin Ali, and Pertev Naili Boratav, consisted of his attempts to define the Turkish race.

In an article called “Türkler Hangi Irktandır? (From Which Race Do Turks Come?) he criticized the widely held belief that claimed Turks were descended from white Aryans, and emphasized that the race issue was a matter of language first of all. He addressed the underlying reason behind the Aryan race theory, which assumed that the Aryans were the originators of civilization, and the belief that Turks had Aryan roots.13 Atsız never shared the embarrassment that the Türk Tarihinin Ana Hatları (Fundamental Contours of Turkish History) 14 (TTAH) felt since the West regarded Turks
as barbaric invaders.

He especially condemned the histories that referred to ancient history and civilizations in order to prove how the Turks were civilized; for him, efforts to prove that the Turks belonged to the same race – Aryan – as Kurds and Gypsies was shameful. Instead of that racial kinship, he preferred the once-disdained Mongols, at least
they had been gifted militarists like the Turks, although this talent had not given the Turks enough time to show themselves in the fields of civilization.16 He argued that children should be raised in the knowledge that their ancestors had been perfect-soldiers of a race called Turan-Altay.

Turkish nationalists are divided to two camps both of which hold hilarious opinions.
