The holocaust was an extremely violent act of prejudice against Jews from Germans, there were almost 6 million Jews killed and even more that weren’t Jews. Scientists did experiments on Jews that usually killed them. Jews were often sent to concentration camps and we killed with poisonous gases and then burnt. Hitler (the ruler of Germany) wanted the world to be a certain race of people (blonde hair blue eyes) he called this the final plan. He would kill anyone he deemed unfit or unattractive.
The Nuremberg trials were the prosecution of people who planned or contributed to the violent actions toward Jews or anyone deemed “unfit to live”
