When the Prime Minister, Winston Churchill announced the end of the war with Germany people were overjoyed.
All across the UK celebrations began. Crowds gathered in public places and there was a lot of singing, dancing and drinking. In fact many pubs completely ran out of alcoholic drinks.
Huge crowds, many dressed in red, white and blue, gathered outside Buckingham Palace in London and cheered as the King, Queen and their family came out onto the balcony.
Later Churchill was greeted by cheering crowds as he made his way to Whitehall and appeared on the flag-covered balcony of a government building.
The partying carried on into the night. After dark, huge crowds continued to meet up at some of London's well known monuments. These were floodlit specially for the occasion.
There were fireworks, too, and images of Hitler were burned on bonfires around the capital.
