"Anne Franks Dagbog" er skrevet af den purunge, jødiske pige, der måtte gå under jorden i Amsterdam i 1942. Ingen anden bog giver en så menneskelig og følsom skildring af jødernes vilkår under Anden Verdenskrig. På sin 13 års fødselsdag fik Anne Frank en dagbog, som hun straks tog i brug. Det blev starten til denne gribende beretning om hendes families dagligdag i deres skjulested i "Baghuset" og deres frygt, angst og håb frem til august 1944, hvor familien blev angivet og deporteret. Kun Annes far overlevede krigen og udgav i 1947 første gang datterens dagbog, der siden er udkommet i utallige udgaver og på alverdens sprog.
"Anne Franks Dagbog" er et af de vigtigste vidnesbyrd om udslettelsen af Europas jøder under 2. verdenskrig. Den skildrer et liv på flugt, et liv under jorden. Alligevel opfatter Anne ikke sig selv som et offer, men fremtræder som en livlig, klarsynet og selvstændig ung pige med sine problemer, længsler, drømme og håb - hvilket blot gør hendes vidnesbyrd endnu stærkere.
Annelies Marie Frank was a German-born Jewish girl who kept a diary documenting her life in hiding amid Nazi persecution during the German occupation of the Netherlands. A celebrated diarist, Frank described everyday life from her family's hiding place in an Amsterdam attic. She gained fame posthumously and became one of the most-discussed Jewish victims of the Holocaust with the 1947 publication of The Diary of a Young Girl (originally Het Achterhuis in Dutch, lit. 'the back house'; English: The Secret Annex), which documents her life in hiding from 1942 to 1944. It is one of the world's best-known books and has been the basis for several plays and films. Frank was born in Frankfurt, Germany, in 1929. In 1934, when she was four-and-a-half, Frank and her family moved to Amsterdam in the Netherlands after Adolf Hitler and the Nazi Party gained control over Germany. By May 1940, the family was trapped in Amsterdam by the German occupation of the Netherlands. 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 concealed rooms behind a bookcase in the building where Frank's father, Otto Frank, worked. The hiding place is notably referred to as the "secret annex". Until the family's arrest by the Gestapo on 4 August 1944, Frank kept and regularly wrote in a diary she had received as a birthday present in 1942. Following their arrest, the Franks were transported to concentration camps. On 1 November 1944, Anne Frank and her sister, Margot, were transferred from Auschwitz to Bergen-Belsen concentration camp, where they died (presumably of typhus) a few months later. They were estimated by the Red Cross to have died in March, with Dutch authorities setting 31 March as the official date. Later research has alternatively suggested that they may have died in February or early March. Otto, the only Holocaust survivor in the Frank family, returned to Amsterdam after World War II to find that Anne's diary had been saved by his secretaries, Miep Gies and Bep Voskuijl. Moved by his daughter's repeated wishes to be an author, Otto Frank published her diary in 1947. It was translated from its original Dutch version and first published in English in 1952 as The Diary of a Young Girl, and has since been translated into over 70 languages.
