The Holocaust is another word for the persecution of the Jews. Nazi-Germany committed genocide (extermination of a group) during WWII.
Six million Europeanen Jews were killed by them. The victims included 1.5 million children. The Nazis not only killed Jews but also gypsies, communists, homosexuals, political dissidents and people with a handicap were all victims of the mass murders.
One of the most famous victims of the Holocaust is Anne Frank. Annelies Marie (Anne) Frank (12 June, 1929 - February or March 1945) was a Jewish girl who was born in Germany. She fled from Germany with her family. They went into hiding in a house in Amsterdam due to the fear of the Nazis. From 1942 to 1944 Anne wrote her diary there, that was found after her deportation. It was published in 1947. Anne Frank's book has been translated into many languages. The Achterhuis (Secret Annex) in Amsterdam is now a museum. http://www.annefrank.org/.
