How did this iron curtain affect Eastern Europe?

The Iron Curtain symbolized the division between Eastern and Western Europe during the Cold War, leading to significant political, economic, and social impacts in Eastern Europe. Countries in this region fell under Soviet influence, resulting in the establishment of authoritarian regimes and limited political freedoms. Economically, these nations experienced centralized planning that often led to inefficiencies and stagnation, hindering growth and development. This divide also fostered a sense of isolation from the West, impacting cultural exchange and the overall quality of life for their citizens.
