When Germany invaded Poland they killed most of the educated people, to make sure that nobody could revolt. After a few months, they found out that the resistance had not disappeared. To punish the Polish people that revolted they created the first of three camps in the neighborhood of Auschwitz. The first gassing took place in this camp, and most administration of all the 3 camps took place here. Therefore it is the most well-known of the camps. Many Polish prisoners died here.
