But she was eventually captured and she died in a Nazi concentration camp.
The Anne Frank Declaration is all about celebrating Anne Frank's life and Josh went along to find out more about it.
"I came to the Anne Frank Declaration for Young People because my school nominated me.
Special diary
I was very moved by the Diary of Anne Frank.
Anne Frank had been through some terrible things.
I read that in the Second World War she hid from the Germans in a secret annex behind her father's office.
Step-sister
I was asked lots of questions for a radio show and people took lots of photos of me.
Before I went to the Declaration I wanted to go to Amsterdam to see Anne's hiding place in the secret annex.
And now I have come to the Declaration I want to go even more than I wanted to before, because it was so good and I want to know more about her life.
I liked going to the Declaration and reading about all the people who have done good things for other people.
I don't hate anyone and this day has shown me this even more."
