Annelies Marie Frank (12 June 1929 – c. February or March 1945) was a German-born Jewish diarist and Holocaust victim. She gained worldwide fame posthumously for keeping a diary documenting her life in hiding during the German occupation of the Netherlands. In the diary, she regularly described her family's everyday life in their hiding place in an Amsterdam attic from 1942 until their arrest in 1944.
Frank was born in Frankfurt, Germany, in 1929. In 1934, when she was four and a half, Frank and her family moved to Amsterdam after Adolf Hitler and the Nazi Party gained control of Germany. By May 1940, the family was trapped in Amsterdam due to Germany's occupation. Frank lost her German citizenship in 1941 and became stateless. Despite spending most of her life in the Netherlands and being a de facto Dutch national, she never officially became a Dutch citizen. As persecutions of the Jewish population increased in July 1942, the family went into hiding in rooms concealed behind a bookcase in the building where Frank's father, Otto Frank, worked.
