The Holocaust took place primarily in Germany and Poland, but also in other countries that the Germans occupied during World War II. At first, most victims were lined up and shot, but later victims were sent to camps where they were executed with poisonous gas.
The Holocaust is known as one of the greatest tragedies of human history. Led by Adolf Hitler, the Nazi party rose to power in Germany and attacked surrounding European nations. The party's agenda was to eliminate what in their opinion were "inferior humans," referring to Aryan people as the superior race. The Holocaust spanned from 1937 to 1945.
