Step-by-step explanation:
The Holocaust, also known as the Nazi genocide, was a systematic and state-run murder of over six million Jewish people and millions of other minority groups, including Catholics, people with disabilities, and LGBTQ people during World War II. It was a form of genocide that was characterized by both the intent to exterminate a group and the function of exterminating a group, intentional or not. Hitler's Nazi regime used forced emigration, concentration camps, and mass executions in gas chambers to carry out their goal of eradicating European Jewry.
