During World War II numerous individuals, states and people worked with fascist forces under different circumstances and with different motives. On the area of the Soviet Union, during that war conflict, it was noted that, among others, Chechens and Tatars collaborated with the Nazi occupier. The work investigates the nature of cooperation between Chechens, Crimea, and Volga Tatars and the Third Reich, specifically through political, cultural, military and other forms of cooperation. Foundations of the work are built on the explanation of the nature of fascism as an ideology and the key reasons of its emergence and expansion. Connected to that is the writing of the complete history of Chechen and Tatar relations with Russians, and Soviets through which it is proven that it is a history marked with conflict that had its culmination in the time of World War II, through the cooperation with the Nazis. Deeper, ideological reasons of cooperation are revealed through the explanation of the link between political Islam and fascist ideology, respectively the key actors of that age. The continuation of the work brings a concrete description od the cooperation between Chechens, Volga, and Crimea Tatars and the forces of the Third Reich so it can be proven that the cooperation with the fascist forces in these cases was used as means to achieve freedom from the Bolshevik rule and to create national states. The work shows that there was no close commitment to fascism in the case of Chechens or Volga and Crimea Tatars.
