Czechoslovak politics reflected a new national situation in Macedonia as early as in the interwar period. However, as a small country which primarily needed to take care of itself, it did not make any official statements on the situation. Czechoslovak politics supported the Yugoslav opinion – Yugoslavia was an ally of Czechoslovakia in the trilateral pact known as 'Little Entente'. After 1945, Czechoslovakia established intensive relations with Yugoslavia and attempted, within their scope, to establish cultural relations between Czechoslovakia and Macedonia; unfortunately, this process was interrupted by the conflict between the USSR and Yugoslavia in 1948. In the 1950s, Czechoslovakia maintained a pro-Bulgarian position, which changed in the 1960s. Czechoslovak politics officially acknowledged the existence of the Macedonian nation and the Macedonian language. This position did not change after the Soviet invasion with Bulgarian participation into Czechoslovakia in 1968 and the establishment of a neo-Stalinist regime known as normalization.
