The Iron Curtain refers to the ideological and physical boundary that separated Eastern and Western Europe during the Cold War, symbolizing the division between the communist Soviet bloc and the capitalist Western nations. This term embodies not only the political and military tensions of the time but also the deep cultural, economic, and social divides that arose as a result of opposing ideologies. The Iron Curtain became a powerful metaphor for the stark differences in governance, society, and international relations that emerged after World War II.
