As you can realize, this is Auschwitz. The greatest concentration camp that is now on the World. This camps were created by Germans with the only purpose of ending with our race, the Jews and anyone that could be different from them.
Welcome to Auschwitz ugly Jews.
For explaining in a short way, the ideology of Nazism was based on how races like Jews were thought as irrelevant. Germans believed they were the "master race" and they were able to finished with roma's. Jews etc.
The consequences that this frustrating and violent episode led in history in terms of geography are very important. The Soviet Union had control of Estonia, Lithuania, Latvia and part of Finland. Poland recover some territories they lost against Germany. Germany was divide into 4 influence areas.
Europe was very unstable after the WWI and this led to more conflicts with the powerful countries.
This tragic event started in 1939 and ended in 1945, leading Germany as defeat.
Hitler was the most influential person in this war, leading the racism created.
The most important consequences of the Holocaust were the 6 million jews that were killed, Europe had great economical problems, there important cities were completely destroyed. Fascist governments disappear.
As a conclusion, there are several ideas that can be analyzed. The first one is that this event led many problems along the world in terms of culture, economy politics etc. After this war, many things had to be reconstructed marking the world history. Adolf Hitler also passed to the history for being one of the baddest mens that have lived on earth, ordering to kill around of 12 million people and extermination of many races.
