Answer:
Step-by-step explanation:
I don't know why, but I can't see another answer given and this is an important question.
The Holocaust, as far as I know, was the first Holocaust but not the last, which used scientific methods and procedures to study and enact the annihilation of a perceived enemy. It was very successful in its objectives killing nearly 1/2 the European Jewish population. The Holocaust was planned on January 20, 1942 in Wannsee, Germany where it was decided that the Jews would be murdered, rather than be deported, which was what was originally the plan. In just over three short years the plan at Wannsee was carried out more "completely" than any Holocaust before it.
This was 4 sentences, but I could not do it any less. This was horrific and goes down as one of the most terrible and inhumane events of the 20th Century. Mind you, there were quite a number of historical events that could be classified the same way.
