The Cold War was a long period of rivalry between two superpowers.

These were the United States and the Soviet Union. They had different ideas about how to run their countries and economies. One side followed capitalism, while the other followed communism. This rivalry is called a "cold war" because the two main countries never fought each other directly in a large war. Instead, they competed through many different ways. They raced to build better technology and more weapons. They also used spies and propaganda to win over other people.

This competition worked through many different types of struggle. Both sides tried to gain influence in other parts of the world. They often supported opposing sides in smaller regional conflicts. These were known as proxy wars. The two nations also competed in a technological race called the Space Race. They used economic aid to try and win the loyalty of other countries. Sometimes, they used sports or diplomacy to show their strength. Even their military alliances were part of the competition. This made the whole world feel divided into two different groups.

This period began right after the Second World War ended in 1945. Before the war, the United States and the Soviet Union were actually allies. After the war, they began to disagree about the future of Europe. By 1949, the Soviet Union had installed its own governments in Eastern Europe. This created a division called the "Iron Curtain." The United States responded with new plans to help and protect its allies. In 1947, President Harry S. Truman introduced the Truman Doctrine to stop the spread of communism.

Many specific events happened during these many years. In 1948, the Marshall Plan gave billions of dollars to help rebuild Western Europe. In 1949, the NATO military alliance was formed by the United States and its allies. The Soviet Union responded by forming the Warsaw Pact in 1955. There were many tense moments, like the Korean War from 1950 to 1953. Another very scary moment was the Cuban Missile Crisis in 1962. This was the closest the world ever came to a nuclear war.

The Vietnam War was another long conflict that lasted from 1955 to 1975.

Eventually, the world began to see big changes. In the 1970s, a period called détente helped the two sides sign treaties to limit weapons. In 1985, Mikhail Gorbachev became the leader of the Soviet Union. He worked to expand political freedoms for his people. This led to many revolutions in 1989 across the Eastern Bloc. Finally, the Soviet Union dissolved in 1991. This event officially ended the Cold War. The Russian Federation then became the successor state to the Soviet Union.
