A few years after Adolf Hitler had come to power in Germany as the Chancellor in 1933, his Nazi Government started policies that were mainly targeting the German-Jews and others that were seen as the enemies of the Nazi regime. In the next ten years the policies had increasingly grown repressive and violent, that by the end of the First World War the estimates of the German/European Jews who were murdered was way over Six Million of them and also this along with approximately 4 Million non-Jews. The Nuremberg Trials were held between 1945 and 1949 where the Allied countries that were on the winning side of the War, they put to trial the German military leaders and those that were involved in the German killing of Jews this list of people included industrialists, investment bankers, and also included physicians who were involved in the human experiments. As part of their way to systematically kill of peoples that they deemed impure or dangerous to the Nazi Regime, they used concentration camps where they murdered their victims in gas chambers and had they bodies incinerated.
By the end of 1942, the Allied Powers during the 2nd World War, consisting of Great Britain, the Soviet Union, France and the United States of America had signed a declaration, after they saw that they could win the war. The Declaration was mainly about the mass murder of European Jews and the local populations. At first each country wanted a to have their own different way of punishing Nazi Germany after the war, for example the Soviet Union at the time, Joseph Stalin wanted to have an execution of more than 500,000 Nazi officials and those that had helped the Nazi in such inhumane acts, while Winston Churchill, the Great Britain Prime Minister only wanted the execution of the high ranking Nazi officials without any possibility of a trial whatsoever. .
There were several legal and procedural hindrances that were to be solved in order that the Nuremberg trials were conducted in the way that the 4 winning States wanted.
