Why is the timeline so important during the holocaust: ? what is happening during the years prior and after?

Holocaust - an important event in history because it killed 6 million Jews in Europe by the Nazis. Hitler was not a hater of Jews. He built this ideology against Jews because of the myth that spread after WW I.

The myth is that Jews and Communists betrayed the German army during the war and that is the reason Germany lost the war. Jews lacked their citizenship and their basic rights, after Nazi took the power of Germany and Hitler became as Chancellor.

Nazi killed Jews all over the European countries they have invaded. Nearly, 80% to 85% of Jews killed during the Holocaust period. During WW II, the Germans troop surrendered to Russia.

After seeing the defeat Hitler took his own life and that's ended WW II. Jews who were in the concentration camps rescued and the Nazi officials charged for crimes against humanity and peace.
