The Frank family moved from Germany to Holland's capital, Amsterdam in 1933. This was the same year that the Nazis grew powerful in Germany. By the beginning of 1940, because of the Nazi occupation of the Netherlands, the Frank family was trapped in Amsterdam. Persecution of Jewish people increased in July 1942, and the family decided to hide. They hid in some secret rooms of her father Otto Frank's office building. After two years, they were betrayed and taken to concentration camps. Anne and her sister, Margot, were later taken to the Bergen-Belsen concentration camp. There, they both died from typhus in February 1945.
