Anne Frank was a thirteen-year-old girl who recorded her thoughts and experiences while hiding from the Nazis during World War II in a diary, which was published by her father after her death. Her tone when she describes herself and her life is fairly playful and humorous, although she is able to be serious and understand the gravity of her situation. Her writing style is personal, honest, and direct. Anne writes because she feels unable to confide in her peers or family; she struggles with the criticism she receives from adults when her family is in hiding, and she is unsure how to reconcile her identity as both Dutch and Jewish in the context of World War II. Anne is lonely, and within the context of her social isolation, her critical family, and the increasingly dire situation they hide from, she struggles with her identity and development into adulthood. Towards the end of the text, Anne realizes that she has matured during her time in the annex, and become more emotionally mature and independent. Shortly before her family was found by the Nazis, Anne had begun considering the nature of war and anti-Semitism from a philosophical perspective, and her role in a world that seemed to be rapidly changing. Anne Frank died in Auschwitz in 1945, only weeks before the camp was liberated by allied soldiers. Her father, Otto Frank, was the only survivor in his family, and he chose to publish Anne's diary in 1947.
