The Iron Curtain was a major political and physical boundary. It divided Europe from 1945 until the early 1990s. This division emerged after World War II ended. It separated the continent into two distinct sides. One side consisted of many nations controlled by the Soviet Union. The other side included many nations that became members of NATO.

Initially, the term described literal physical barriers. These barriers were built along the western borders of the Eastern Bloc. They included razor wire, fences, and fortified walls. Guards also used minefields and watchtowers to monitor the borders.

These structures served to keep people in and keep information out. Over time, the term became a metaphor. It represented a deep divide in ideology, economy, and government. This "differentness" severed cultural connections between European populations.

Many specific nations were located east of this divide. These states were often under the hegemony of the Soviet Union. The Eastern Bloc included Poland, East Germany, Czechoslovakia, Hungary, Romania, and Bulgaria.

The Soviet Union also annexed the three Baltic states: Estonia, Latvia, and Lithuania. In 1955, many of these eastern nations formally joined the Warsaw Pact. This was a military alliance led by the Soviet Union. To the west, many nations were part of NATO.

The term's origin is often linked to Winston Churchill. He was a leader from the United Kingdom. On March 5, 1946, he gave a speech in Fulton, Missouri.

He stated that an iron curtain had descended across the continent. He noted that many capitals of Central and Eastern Europe lay behind this line. However, the phrase had earlier uses. Queen Elisabeth of Belgium used it in 1914. In theaters, iron safety curtains are used to slow the spread of fire.

The division grew from complex political tensions. In 1939, the Soviet Union and Nazi Germany signed the Molotov–Ribbentrop Pact. This agreement included a secret plan to split Poland and Eastern Europe. The Soviet Union then occupied several territories. These included parts of Poland, Latvia, Lithuania, Estonia, and northern Romania.

During World War II, Joseph Stalin wanted a buffer area. He aimed to have pro-Soviet states on his borders. This goal created tension during the Yalta and Potsdam conferences in 1945.

At the Potsdam Conference, the Allies assigned certain territories to Soviet control. These included parts of Poland, Finland, Romania, Germany, and the Balkans. Although Stalin promised national self-determination, Western leaders remained uneasy. Churchill feared the United States might return to isolationism. He worried that exhausted European states could not resist Soviet demands.

This distrust deepened as the Cold War progressed.

Events eventually began to demolish the Iron Curtain. This process started with the fall of communism in Poland and Hungary.

Changes also occurred in East Germany, Bulgaria, Czechoslovakia, and Romania. These shifts led to major political reorganizations. East Germany reunited with West Germany on October 3, 1990. The Soviet Union dissolved itself in December 1991. Czechoslovakia dissolved later in 1992.

Today, the legacy of the barrier has changed. Because human activity was low near the border, nature grew back. These natural areas are now called the European Green Belt.

Some parts of the old border still exist. The Turkish–Armenian border has remained closed since the 1920s. It is sometimes called the last vestige of the Iron Curtain.
