native spiritual roots and Pan-Turkism ideology since the 1990s, especially, in Kyrgyzstan, Kazakhstan, Mongolia, some autonomous republics of the Russian Federation (Tatarstan, Bashkortostan, Buryatia, Yakutia, and others), among the Crimean Karaites and Crimean Tatars. After the 1908 Young Turk Revolution, and especially after the proclamation of the Republic in 1923, a nationalist ideology of Turanism and Kemalism contributed to the revival of Tengrism. Islamic censorship was abolished, which allowed an objective study of the pre-Islamic religion of the Turks. The Turkish language was purified of Arabic, Persian and other borrowings. A number of figures, while they did not officially abandon Islam, adopted Turkic names, such as Mustafa Kemal Atatürk (Atatürk — "father of Turks") and the historian of religion and ideologist of the Kemalist regime Ziya Gökalp (Gökalp — "sky hero"). The prominent Turkish writer and historian Nihal Atsız was Tengrist and the ideologue of Turanism. The followers of Tengrism in the paramilitary organisation Grey Wolves, mainly inspired by his work, replace the Arabic designation of the god "Allah" with the Turkish "Tanri" in the oath and pronounce: "Tanrı Türkü Korusun" (Tengri, bless the Türks!). The most famous modern ideologues and theorists of Tengrism are (1944–2018), (1938–2003), Aron Atabek, (1955–2010), Rafael Bezertinov, Shagdaryn Bira, , (1947–2018), Mongush Kenin-Lopsan, (1958–2016), Choiun Omuraliyev, Dastan Sarygulov, and Olzhas Suleimenov. The poet, literary critic and Turkologist Olzhas Suleimenov, the eulogist of the Kazakh national identity, in his book AZ-and-IA that was banned after publication in 1975 in Soviet Kazakhstan, USSR, presented Tengrism ("Tengrianstvo") as one of most ancient religions in the world. Tengrism has very few active adherents, but its revival of an ethnic religion reached a larger audience in intellectual circles. Former Presidents of Kazakhstan Nursultan Nazarbayev and Kyrgyzstan Askar Akayev have called Tengrism the national, "natural" religion of the Turkic peoples. So, during the 2002 trip to Khakassia, Russia, Akayev spoke out that a visit to the Yenisei River and the runic steles constituted "a pilgrimage to a holy place for the Kyrgyz" just as the pilgrimage to Mecca. Presenting Islam as foreign to the Turkic peoples, as Semitic religion together with Christianity and Judaism, adherents are found primarily among the nationalistic parties of Central Asia. Tengrism may be interpreted as a Turkic version of Russian neopaganism, which is already well-established. It is partly similar to the new religious movements, such as New Age. In Tatarstan, the only Tengrist periodical Beznen-Yul (Our
