After 1945 Europe split into two camps that never quite fought each other directly but glared across an 'iron curtain' for decades. The Cold War divided families and cities — Berlin literally cut in half by a wall — into East and West.
A war without direct battle
After 1945 the wartime alliance between the United States and the Soviet Union collapsed into rivalry. Europe split into a Western, capitalist, US-aligned bloc and an Eastern, communist, Soviet-aligned bloc — a division Winston Churchill called an 'iron curtain'. The two never fought directly but competed through arms, ideology, and proxy conflicts.
Divided Germany — and the Berlin Wall built in 1961 — became the Cold War's symbol. Its fall in 1989 signalled the collapse of communist rule across Eastern Europe.
NATO (1949) bound the Western bloc; the Warsaw Pact (1955) bound the Eastern. The USSR itself dissolved in 1991.

Order the Cold War milestones from the iron curtain to the wall's fall.
- Note the two superpowers never fought each other directly.
- Recall how they competed instead — arms races and proxy wars.
- Explain why historians call it a 'cold' war.
What you should see: It was 'cold' because the superpowers avoided direct 'hot' combat, competing through deterrence, ideology, and proxy conflicts rather than open war between them.
