I think that one of the final outcomes of the Holocaust was that it helped to make the word "genocide" something of a political reality that became unavoidable. In most learned circles, you cannot go very far in talking about the denial of individual rights, the unchecked power of the executive, and the notion of silencing voices without mentioning the Holocaust. It becomes the ultimate reminder of what happens when a world loses institutional checks and safeguards. At the same time, I think that another one of the final outcomes of the Holocaust was a new visualization of what happens when private cruelty meets public cruelty. The Holocaust is a stark reminder of terror on multiple levels, and this is one of its lasting legacies. The numbers of the dead and forgotten are staggering. Yet, it is within the individual stories of those walking to the crematorium, or those loaded onto trucks and trains, or those who were separated in the lines that reminds us that political cruelty carries with it a very real and human face of private torture. This convergence of reality is where we see the Holocaust in its most stunning and unforgettable moments.
Humanity has learnt a lesson
First of all, there was the period of unification in Europe during 16th century onwards with the Absolutist states rising into power. Each nation wanted to strengthen themselves by uniting the people, this step led ultimately to the banishment of Jews from many countries like Spain, Italy and many thousands were killed in Germany by Hitler's army on grounds of religious unity. The final outcome of the Holocaust was the decline in Europe's population and as a result the economy of Europe also suffered.
