Following the Second World War, the world became bipolar, and a cold war began between the USA and the Union of Soviet Socialist Republics. The whole world was affected by the fierce competition, which was directed by two centers with different rival ideologies and included activities to expand their spheres of influence. Especially in the countries that participated in the Western Bloc, the establishment and strengthening of many organizations were supported by the Warsaw Pact in order to increase the sympathy of the people for socialism and to influence the country administrations, and it was tried to gain effectiveness by causing chaos in these countries. Therefore, in different countries, many simultaneous marginal movements with similar activities emerged. Likewise, similar movements were observed in different socialist countries, despite being very few. In these movements in foreign countries, which created a model for the organizational structures and activities in Turkey, the left-wing organizations in these foreign countries were taken as models especially in the first establishment, intellectual development, determination of the movement style and organization schemes of the first marginal left-wing organizations that emerged in Turkey after the 1960s.
