The Nazi government kept removing the rights of those they wanted to "get rid of", while using propaganda to convince the general public that it was in Germany's best interest.

Nazis ordered all Germans to boycott any business that was owned by Jews, and Jews lost all their rights to vote.

Jews could no longer own businesses, so Jewish business were either closed or Jews would have to give up their ownership. In some cases they would sell at an extreme financial loss, to their Aryan partners or neighbors

Jews had to follow curfews, give their radios to the police, and were forced to wear yellow stars of David, which followed the tragedy of Kristallnacht on November 9th, 1938( a government-sponsored attack on Germany's Jewish population, resulting in the destruction and burning of Jewish businesses and synagogues, and the arrest and terrorizing of many Jews).

Nazis began deporting German Jews to Poland, and began to put Jews into ghettos and then concentration camps through Europe.

Jews were forbidden to subscribe to newspapers or own typewriters; they could not own bicycles, or use public transportation.

By the end of the year, over 80 percent of the jews who would die in the Holocaust had been killed.

Even as Hitler was losing war, he managed to take over weakened Hungary, sending 12 thousand Hungarian Jews to be murdered a place called Auschwitz.

War crimes trials began in Nuremburg. At these trials, the world community was left trying to assign responsibility for the crimes of World War One.

If we were gonna have another Holocaust, we would have to think of a way to stop it. One way to stop a Holocaust would be to make a speech and talk about why we should not care about another person religion etc. Another way would be to make posters or billboard or something that would catch your eye saying something like, "How would you feel if we were against you because of your skin color or something?" Which may make them rethink and stop hating on a group of people.
