East Germany opened the Berlin Wall on November 9, 1989, letting crowds cross freely and signaling the collapse of communism in Eastern Europe.
See it on the Battles & Wars map →What happened
The Wall had divided Berlin since 1961; at least 140 people were killed at it trying to escape or in related incidents. In 1989 Hungary opened its border, East Germans fled west, and mass protests spread. On November 9 a party spokesman, Günter Schabowski, mistakenly announced at a press conference that new travel rules took effect 'immediately'. Crowds gathered at the checkpoints and overwhelmed guards opened the gates. Germany reunified on October 3, 1990.
Why it matters
It became the symbol of the Cold War's end; within about two years communist governments across Eastern Europe fell and the Soviet Union dissolved.
How we know
Live television and press coverage, the recorded Schabowski press conference, East German party and Stasi archives opened after 1990, and preserved Wall sections and memorials in Berlin.
Still debated
How much credit goes to Gorbachev's restraint, Western pressure or East Germans themselves remains debated, as does how close it came to violence.

▸Fall of the Berlin Wall signaled the end of Cold WarWell documented
The connection
The Wall had been the starkest symbol of a divided Europe. Its opening showed the Soviet Union would not use force to hold its satellite states. Communist governments across Eastern Europe fell within months, Germany reunified inside NATO in 1990, and the Soviet Union dissolved in December 1991.
When and how
Berlin, November 9, 1989; the Malta summit of George H. W. Bush and Gorbachev in December 1989; German reunification on October 3, 1990.
How we know
Leaders' statements, the 1990 Two Plus Four Treaty and the Soviet dissolution are fully documented.
Debates and open questions
When exactly the Cold War ended, 1989, 1990 or 1991, is a matter of definition, and so is which side 'won' and why.
▸Fall of the Berlin Wall cleared the way for a UN coalition in Gulf War (Operation Desert Storm)Mostly agreed
The connection
With the Cold War ending, the Soviet Union, once Iraq's main arms supplier, did not veto UN action. For the first time in decades the Security Council's permanent members largely agreed, authorizing force against Iraq in Resolution 678, and the US could move forces from Europe to the Gulf.
When and how
UN Security Council, New York, November 29, 1990; the US VII Corps moved from Germany to Saudi Arabia in late 1990.
How sure are we?
Security Council voting records show Soviet support and China's abstention; US deployment records document forces sent from Europe.
Debates and open questions
The Wall itself did not cause the war; the link runs through the wider Cold War thaw, and how much Soviet cooperation mattered is debated.
▸The 'Last Supper' and the 1990s defense mergers followed the budget cuts after the Fall of the Berlin WallWell documented
The connection
When the Berlin Wall fell in 1989 and the Soviet Union collapsed in 1991, the threat that had justified high spending vanished. US weapons-buying budgets fell by more than half from their mid-1980s peak, which led the Pentagon in 1993 to tell contractors to merge or fail.
When and how
Washington, 1989–93; 'peace dividend' cuts under Presidents George H. W. Bush and Bill Clinton, with Defense Secretary Les Aspin and his deputy William Perry.
How we know
Defense budget data and the accounts of Perry, Augustine and others tie the merger push directly to the post–Cold War cuts.
Debates and open questions
Whether the 'peace dividend' cuts went too deep, leaving too few suppliers for later wars, is debated.
