The Holocaust is also known as the Shoah was the genocide of European news during world war II. Between 1941 and 1945, Nazi Germany and it's collaborators systematically murdered some six million jews across German occupied Europe around two-thirds of Europe's Jewish population.

The murders were carried out in pogroms and mass shootings, by a policy of extermination through labor in concentration camps, and in gas chamber s and gas vans in German extermination camps. 

The Nazis targeted news because the Nazis were radically antisemitic. This means that they were prejudiced against and hated jews.

The Nazis falsely accused the Jews of causing Germany's social, economic,  political, and cultural problems. Between 1933 and 1945, Nazi Germany and its allies and collaborators implemented a wide range of anti-jewish policies and measures.

These policies varied from place to place. Thus, not all jews experienced the holocaust in the same way. But in all instances, millions of people were persecuted because they were identified as Jewish.
