Anti-Semitism has been around for a long time, much longer than World War II. the Nazi party picked up this anti-Semitism and began to blame the problems of Germany on the Jews. Germany had just lost World War I and was in shambles. They lost so much afterwards and when someone like Adolf Hitler came to vie for power he was welcome. One of the first things he did was give the people someone to blame for their problems. They took onto it like never before. Although it would seem like all of Germany held this view, given the carnage that occurred, but really only a small part of Germany held this view. Many were able to support the idea of "the Jews" being at fault, but more like a broader sense than actual violence against the Jewish people. There were enough people who hated the Jewish people within the party for the Holocaust to happen.
One explanation for how the Holocaust was allowed to happen was fear. It's one of the more popular reasons. They tried to say they were too scared to disobey the Nazi party, but it was never proven that there were any punishments for refusing to kill the Jews. When it came to people protesting about just the Jews they didn't really have anything happen to them. Really the people who knew about the situation just ignored them. It wasn't considered a priority to them.
Another reason shown was that they had something to gain from what happened to the Jews. All the valuables the Jewish people had to leave behind was now open for the German people. They also had more land and jobs available for them. People are willing to overlook anything in the face of their own greed. In recent years historians learned that there were public auctions for the sudden increase in treasures.
Probably the strongest reason for the Holocaust to happen was the deference of authority. People did not want to diverge from the group and also wanted to please the people in charge. They wanted to conform and when they committed atrocious acts were then able to rationalize their actions to themselves. This way they did not see their actions as very bad, but something that might even be necessary.
Hopefully nothing like this ever happens again.
