Anne Frank received a diary as a gift for her 13th birthday in 1942. She began writing in it two days later, just before going into hiding with her family and another family to escape Nazi persecution of Jews in Amsterdam. The eight people hid in concealed rooms behind a bookcase in Anne's father's office building for over two years before being betrayed in 1944. They were all arrested and deported to concentration camps, where Anne and her sister Margot died of typhus in Bergen-Belsen in March 1945, just weeks before it was liberated. Only Anne's father Otto survived. Anne's diary was published after the war and brought international attention to her experience of living in hiding during the Holocaust.
