V-E Day (Victory in Europe Day) marks the formal acceptance by the Allies of Nazi Germany's unconditional surrender. The surrender documents were first signed in Reims, France, on May 7, and again in Berlin on May 8. Millions of people across the globe poured into the streets to celebrate the end of a conflict that had lasted nearly six years and claimed tens of millions of lives. In London, crowds filled Trafalgar Square and the Mall, with Princess Elizabeth and Princess Margaret joining the celebrations incognito. While the war in Europe was over, Allied leaders reminded the public that the war against Japan was still ongoing, requiring further sacrifice. The day remains a major anniversary of peace and liberation in many European countries.
