The epochal meeting in the capital of Finland marks a turning point in international relations during the Cold War. On August 1, 1975, representatives from 35 countries in North America and Europe signed a fateful document that redrew the political map of the continent.

The Helsinki Final Act established an unprecedented mechanism for monitoring human rights, bringing together states from opposing military alliances - NATO and the Warsaw Pact. Bulgaria was among the key participants in this international forum, which later became a catalyst for democratic changes.

The agreement guaranteed the inviolability of national borders and created an unprecedented platform for dialogue between East and West. Experts later defined this document as strategically important, which prepared the ground for political transformations in Eastern Europe in 1989.
