The Second World War has left an indelible mark in the whole world. The millions of victims and the genocide of a large number of Jews and other people considered by the German leadership as inadequate, will forever be remembered. How is it possible that such horrific crimes occurred in front of the eyes of the Allies in the so-called „total war“, it will be shown in this master thesis. From the very beginning of the Second World War, it was clear that Adolf Hitler had a vision of the German state in which it had places only for the most adequate citizens, those who met the vision of Hitler himself and the people around him. The focus of this paper was put to the Final Solution - a Nazi plan to destroy the entire Jewish population in Europe during World War II. Furthermore, the paper will show which decisions have influenced the development and adoption of the Final Solution that resulted in the Holocaust and the mass executions of an unbelievably large number of people. When Adolf Hitler became the German Chancellor in 1933, the influence and power he gained helped his plans to spread his anti-Semitic beliefs between his supporters. Thus, he first initiated the displacement of the Jews within Germany on the foreseen places, to move them from their own homes, villages and cities in which they lived their whole lives. In 1938 he succeeded in displacing the Jews and seizing their assets, depriving them of their careers and fundamental human rights. Next, in 1939, a document was issued that ordered all Jews in German occupied part of Poland to move to the so-called ghettoes where they lived in inhumane conditions, and where a very large number died of starvation. As long as the Jews were deprived of their fundamental human rights during the first years of the war, there was no official document in which the annihilation of the Jewish people would be strictly prescribed. After the German attack on the Soviet Union in 1941, mass murders of Jews began on the Soviet territory. Reinhard Heydrich was given the task of writing a document containing all the items to solve the Jewish question in both Europe and all parts of the world under German rule. What this meant to the world and how this might have happened not so long ago, you will find out in this paper. Key words: Final solution, Jews, Holocaust, World War II
