The aim with this research is to investigate how knowledge about the Holocaust is expressed in history teaching. The method we have used in this essay is to examine how others have researched this subject. We have used different research articles and articles from different countries, this is because teaching about the holocaust is not limited to just Sweden.There is a lot of research concerning the holocaust, but there are not many articles that relates to the specific topic that we had, so we had to narrow our articles down. We choose articles that focused on teaching and teaching materials, either by books or visiting a historical place connected to the holocaust. As we can see in the conclusion, most nations teach about the holocaust in different ways. This is because they have different historical backgrounds, and they have different ways on how to approach the holocaust.
